AB  - This work aims to design an electrochemical sensor for pesticide detection in food and water based on modified pyrophyllite. Pyrophyllite is a phyllosilicate mineral of the chemical formula Al2Si4O 10(OH) 2. Modification of the carbon paste electrode was made by the addition of mechanochemically modified pyrophyllite. This type of modification is an environmentally friendly green chemistry method because it avoids using solvents. It was found that the best physicochemical characteristics for constructing the electrochemical sensor were shown by the sample that was milled for 15 minutes. Due to the delamination and bending of the layers, the size of the particles and crystallites decreases, and the electrocatalytic activity of the modified electrode is improved. Electrochemical measurements were performed by cyclic voltammetry in 0.5 mol/L H 2SO 4 and 1 mmol/L K 4Fe(CN) 6 in 0.1 mol/L KCl. The results showed that the electrode made of 50 % carbon paste and 50 % mechanochemically ground pyrophyllite for 15 minutes had the best properties. Quantitative detection of carbendazim was done by differential pulse stripping voltammetry at different pH in the Britton Robinson buffer. The developed method shows the linearity at pH 4 in the range of (1–10) mg/kg, with r = 0.999 and a detection limit of 0.3 mg/kg. In contrast to earlier works, in which carbendazim was determined electrochemically with different types of electrodes, the detection limits obtained with the carbon paste electrode modified with pyrophyllite, which was ground for 15 minutes in this work, are significantly lower

AB  - In this work, a hybrid pyrophyllite/AgNPs system was designed by mechanochemical activation of pyrophyllite, Al2Si4O 10(OH) 2. Tuning this system’s properties is especially important in terms of possible biomedical applications. The reaction was triggered by adding 2, 5, and 10wt% of silver in the form of AgNO3, indicating green synthesis of AgNPs. Thereby, the grinding time was adjusted from 20 to 320 minutes. The collected samples were analyzed by FTIR, XRD, SEM with EDX, TGA, DTA and PSD. The FTIR spectra of the pyrophyllite/AgNPs system showed the disappearance of some bands characteristic of pyrophyllite itself due to breaking of some bonds during the grinding, and the appearance of some new bands. SEM-EDS analysis confirmed that pyrophyllite structure changed during the mechanochemical treatment, indicating a homogeneous distribution of silver along the analyzed surface. PSD analysis showed that the average particle size distribution is approximately the same for all samples, despite the different wt% of silver. While XRD patterns of samples with 2 and 5 wt% of AgNO 3 did not show reflections originating from silver, the peak at 38.16˚ of the pyrophyllite sample milled for 20 minutes with 10 wt% of silver could be assigned to silver in the metal form. DTA curves of pyrophyllite/AgNO 3 samples milled for 20, 80 or 320 min had similar shapes for different silver content added. TGA curves of pyrophyllite/AgNO 3 samples milled for 20 min with 2, 5, and 10 wt% of silver showed a total weight loss of about 10% while for samples milled for 320 min reduced weight loss was observed due to the agglomeration of particles.

AB  - The paper deals with the destabilization methods for improving the storage properties of metal hydrides. The experimental approach was used to point out the influence of various types of defects on the structure and stability of hydrides. As a case study, Mg-based hydrides have been investigated. As shown by our research, ion irradiation is the way to introduce a well-defined concentration of defects (Frankel pairs) at the surface and sub-surface layers of a material. Defects at the surface play the main role in sorption reactions since they enhance the dissociation of hydrogen. Further, our research shows that ball-milling introduces defects through the entire sample volume, refines the structure and thus decreases the path for hydrogen diffusion. Surface-modified material demonstrates better thermodynamic and kinetics properties than bulk modified hydride materials.

AB  - Adsorption, a highly efficient water purification method and tool for pollution control, utilizes materials like clay. Compared to other commercial adsorbents, clay offers notable advantages including affordability, large specific surface area, accessibility, high ion exchange capacity, excellent adsorption properties, and non-toxicity. Pyrophyllite, among abundant natural clays, stands out due to its layered structure without interlayer cations or water molecules, offering favorable physical and chemical attributes. This study specifically examines the characterization of natural pyrophyllite ore treated with ultrasonic waves for 30 minutes and 6h. Analysis of samples using X-ray diffraction (XRD) technique indicates the removal of hard phases such as quartz and calcite from both treated samples in comparison to the raw ore. Energy dispersive X-ray spectroscopy (EDS) analysis, conducted as part of SEM-EDS analysis, revealed a significant reduction in the weight % of silicon. Specifically, the Si content decreased from 35.1 weight % in the raw ore to 28.7 after half an hour of treatment. Subsequently, after 6 hours, the most effective purification was achieved, with the Si content reaching only 18.6 weight %. Furthermore, UV-VIS analysis testing the sorption of a methylene blue solution in water reveals that ultrasonically treated pyrophyllite for 30 minutes achieves 97% efficiency after 24 hours, surpassing the 89% efficiency of the raw ore. Notably, after 6 hours of ultrasonic treatment, efficiency reaches nearly 98% after just 1 hour, confirming high efficacy of ultrasonic treatment on adsorption ability of pyrophyllite.

AB  - The influence of the addition of nickel on hydrogen desorption from the MgH2–Ni composite was investigated. The composite powder was ball-milled for 15, 30 and 45 min and characterized by XRD, SEM-EDS, PSD, DSC and TPD methods. It was observed that the uniform distribution of nickel decreases hydrogen desorption temperature by more than 100 °C. A kinetic model for the hydrogen desorption process was also determined. The hydrogen desorption reaction in catalyzed samples is described by the Avrami-Erofeev model with the value of parameter n = 4. The apparent activation energy of the hydrogen desorption reaction was decreased with the increase of milling time and the addition of nickel. It has been shown for the first time that two main processes (grinding and the catalytic effect) could be separately analyzed. It is concluded that for investigated short milling times, the catalytic effect of Ni is predominant.

AB  - The effect of pure Ni addition (5 wt.%) in MgH2 powder was investigated mechanochemically for short milling times (15, 30, and 45 min). Obtained MgH2-Ni system was characterized by XRD, SEM-EDS, PSD, DSC, and TPD. Compared to pure MgH2, uniform distribution of nickel reduces the temperature of H2 desorption by more than 100 °C. It is shown that influence of two important processes, grinding and catalysis, may be followed separately. We can conclude that the catalysis of H2 desorption by Ni particles on MgH2 matrix is the dominant effect for the investigated short milling times.

AB  - Adsorption has proven to be the best water purification process and is considered a very effective method for pollution control in general. Clay is a natural material that occurs on the earth's surface and consists of hydrated aluminosilicates and other metal oxides such as Fe2O3, MgO and K2O. The use of clay as an adsorbent has considerable advantages over many other commercially available adsorbents. Low price, high specific surface area, availability, high ion exchange potential, excellent adsorption properties and non-toxicity are just some of its advantages. One of the most abundant natural clay materials is pyrophyllite. Pyrophyllite (Al2[Si4O10](OH)2) has a 2:1 layered structure whose layers are electroneutral, so pyrophyllite contains no cations or water molecules in its interlayers. As a result, it has good physical and chemical properties, making pyrophyllite one of the potential materials for the production of membranes for efficient water filtration. This study focuses on the characterization of natural pyrophyllite ore subjected to ultrasonic treatment at different time intervals. The purpose of ultrasonic treatment is to remove hard phases such as quartz and calcite from the ore and thereby improve its sorption capacity. The treated samples were thoroughly analysed using SEM and XRD techniques. It was found that increasing the duration of the ultrasonic treatment was associated with a reduction in the proportion of hard phases in the sample. The results of the UV-VIS analysis were also presented, in which the sorption properties of pyrophyllite ultrasonically treated for 30 minutes were investigated in comparison to the sorption properties of the raw ore. The sorption of a methylene blue solution after 24 hours in water was investigated and the UV-VIS analysis showed that the efficiency of the ultrasonically treated pyrophyllite was 97%, while the efficiency of the raw ore was 89% over the same period. These results indicate that the pyrophyllite has good sorption properties and could be a potential material for the production of membranes.

AB  - In this paper hydrogen sorption properties of Mg–V multilayer thin films are studied. Thin films are synthesized by means of RF magnetron sputtering. Further modification of material is done using low energy H ion irradiation. The hydrogen sorption properties and kinetics are assessed using TOF-ERDA, in situ optical microscopy coupled with TDS, and TEM analysis. The results of TOF-ERDA indicate full hydrogenation of samples, although the presence of oxygen throughout the film is observed. It corresponds to the formation of MgO, also confirmed by EELS results with hydride plasmon peak hindered by MgO peak. Hydrogenation causes severe damage to the surface of the film and fragmentation of the V layer. TDS and optical analysis indicate lower desorption temperatures for thinner films. The desorption onset does not depend on defects concentration. The kinetic analysis further shows that the apparent activation energy for the thinner film is two times lower.

AB  - Pyrophyllite, a naturally abundant clay material, exhibits remarkable physicochemical characteristics. Its minimal electrical and thermal conductivity, low expansion rate, strong mechanical properties, and outstanding heat resistance make it a valuable resource across diverse industries. Pyrophyllite finds applications in sectors such as paper and plastic manufacturing, brick production, ceramics, cosmetics, rubber processing, and wastewater treatment. Furthermore, its versatility extends to the production of ceramic membranes for efficient water filtration. This paper presents the characterization of natural pyrophyllite ore subjected to ultrasonic treatment at varying time intervals. The ultrasonic treatment aims to eliminate hard phases such as quartz and calcite within the ore, thereby improving its sorption capabilities. The treated samples were subjected to analysis using SEM and XRD techniques. Morphological and structural analysis revealed that as the duration of ultrasonic treatment increased, the proportion of hard phases in the sample decreased. Additionally, this study evaluated the sorption properties of pyrophyllite. A comparative analysis was conducted between a raw clay sample containing various admixtures and a sample that underwent a 30-minute ultrasonic treatment. The sorption of a methylene blue solution after 24 hours in water was assessed, with UV-Vis analysis revealing that the efficiency of the sonically treated pyrophyllite exceeded 97%, whereas the raw ore exhibited approximately 89% efficiency over the same duration. These findings suggest that the removal of hard phases from pyrophyllite ore enhances its sorption properties

AB  - The work aims to design a pyrophyllite-modified carbon paste electrode for pesticide detection in aqueous solutions. The structural and morphological characterization of natural pyrophyllite clay for Parsovići mine, Bosnia and Herzegovina, and mechanically modified pyrophyllite was performed using X-ray diffraction analysis (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and particle size analysis (PSD). The electrochemical characteristics of the constructed electrode were investigated using cyclic voltammetry in 1 mM K4Fe(CN)6 in 0.1 M KCl and 0.5 M H2SO4 and differential pulse stripping voltammetry in Britton- Robinson buffer at pH 2-8. It was shown that the maximum at + 0.96 V versus Ag/AgCl originates from oxidation by carbendazim at pH 4 in the Britton-Robinson buffer. The electrode designed in this way showed numerous advantages such as good stability and sensitivity. The developed analytical method is linear over the range of 1 ppm to 10 ppm with r=0.999 and a detection limit of 0.3 ppm.

AB  - Hydrogen as an energy vector represents great potential, due to its high gravimetric density and low mass, as well as the fact that combustion does not emit harmful chemical byproducts. Hydrogen has the highest energy density per unit mass compared to any other fuel but a rather low energy density per unit volume. Further, hydrogen storage is a key technology for developing a hydrogen and fuel cell-based economy [1]. Metal hydrides as alternative hydrogen carriers have a wide range of performance parameters such as operating temperature, sorption kinetics, activation conditions, cyclic options, and equilibrium hydrogen pressure. These parameters can be improved or adjusted to meet the technical requirements of different applications. The most commonly used method for hydride destabilization is nanostructuring by mechanical milling which leads to a reduction in the particle and crystallite size of the MgH2 powder. Nanostructuring is often combined with catalyst addition and composite formation [2,3]. The most of research is focused on the morphological, structural, and thermodynamic effects typical for long milling times, while in this work we have followed the changes taking place under short milling times. The thermal stability of magnesium hydride is related to - changes in the crystallites and powder particle size. The analysis also considered the changes in activation energy. MgH2-M composites were prepared by mechanical milling of the as-received MgH2 powder (Alfa Aesar, 98% purity) with the addition of 2 and 5 wt.% of M (M= V, W, Mo). Mechanical milling was performed in s SPEX 5100 Mixer Mill using 8mm diameter milling ball. Samples were milled for 15-45 minutes under the inert atmosphere of argon and a ball-to-powder ratio 10:1 Figure 1. shows the kinetic curves obtained for composites with 5wt% of vanadium. To investigate the desorption process in detail, different models of solid-state kinetics were used as implemented in the code developed in our group. The ratelimiting step of the desorption reaction was determined using the iso-conversional kinetic method due to better accuracy of obtained apparent activation energies. As shown in Table 1 a decrease in apparent activation energies has been observed. It is obvious that the sorption kinetics is affected by material preparation because the reactivity of magnesium with hydrogen is strongly modified by changes in several surface parameters that govern the chemisorption, the dissociation of molecular hydrogen, and hydride nucleation

AB  - The main goal is to develop electrode material for the detection of traces of pesticides in food and water in a wide range of pH values. The leading idea is to use natural clay pyrophyllite to modify carbon paste electrode. SPEX Mixer/Mill 5100 is used for mechanochemical modification. The changes in the structure of pyrophyllite before and after the grinding process were studied by means of PSD, XRD, FTIR, and DTA-TG [1]. The electrochemical behavior of the sensor was followed using differential pulse stripping voltammetry (DPSV). It is shown that obtained material can be used as electrodes in electrochemical sensors for pesticide detection in a wide range of pH.

AB  - The effect of mechanical milling on the thermal behavior of pyrophyllite ore from a deposit in Parsovići, Bosnia and Herzegovina, was characterized by X-ray powder diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, and Particle size distribution. The thermal behavior of the material was followed by thermogravimetric and differential thermal analysis and correlated to its microstructural properties. The Williamson-Hall model was used to calculate the crystallite size and microstrain. Mechanochemical treatment of pyrophyllite ore produced a substantial structural modification, mainly along the c axis, resulting in disorder and partial degradation of the crystal structure of the ore. The particle size diminution, induced defects, and microstrain in the crystal lattice cause decrease in the peak intensity until the final disappearance. As confirmed by scanning electron microscopy and particle-size-distribution analysis, the surface area and the agglomeration is more pronounced as grinding time increases. Dehydroxylation of the minerals in the unmilled ore was realized at 716oC confirm by FTIR analysis. The endothermic peak that corresponds to dehydroxylation is shifted toward lower temperatures and becomes broad giving rise to the formation of amorphous SiO2 as milling time increases.

AB  - Molybdenum disulfide (MoS2) is considered promising noble metal-free catalysts for the hydrogen evolution reaction (HER). Whereas the bulk MoS2 does not exhibit significant activity, the catalytic properties of various nanostructures are noticeable. Therefore we synthesized flower-like molybdenum disulfide with the simple, one-step hydrothermal method. To enhance the catalytic activity of the material, low-energy ion irradiation is employed. As-prepared MoS2 is irradiated with hydrogen and carbon ions of various energies (20–40 keV) and fluences (1014-1017 ion/cm2). Our results show that irradiation has beneficial influence on MoS2 catalytic activity toward hydrogen evolution reaction. By producing morphological changes and defects in the structure, ion irradiation also impacts the conductivity of the material, which shows predominant effect on hydrogen evolution. The increase of current density at an overpotential of 300 mV with hydrogen ion irradiation is even 6 times higher than for as-synthesized catalyst.

AB  - LiAlH4 was modified by mechanical milling and with the addition of 5 wt.% Fe2O3 in order to improve its hydrogen desorption properties. The composite was milled for 1, 3, 5, 7 or 15min, and depending on the milling time, various phenomena took place. Up to a milling time of 5min, the particle size of the composite decreases. Further milling leads to the particles agglomeration reaching the size of the starting material after 15min. Moreover, the mechanical milling process leads to the transformation of AlH - 4 to AlH 3 - 6 structure as a result of partial hydrogen desorption. Hydrogen desorption during the milling is the most pronounced in the sample milled for 15min, so this sample has only one hydrogen desorption peak in the temperature-programmed desorption measurements.Mechanical milling with the addition of Fe2O3 for up to 15min improves LiAlH4 hydrogen desorption properties as hydrogen desorption temperature and apparent activation energies decrease.

AB  - MgH2 based composites combined with NaNH2 were synthesized by mechanical milling for three different milling times ranging from 15 to 60 minutes. Microstructure and particle size of the samples were analyzed by SEM microscopy while desorption properties were followed by Thermal Desorption Spectroscopy (TDS). The kinetic properties of NaNH2-MgH2 composites were investigated by isoconversional kinetic method as implemented in code developed by our group. Composites show hydrogen desorption peaks shifted to lower temperatures in comparison to mechanically modified and as received MgH2. All NaNH2-MgH2 composites show enhanced kinetics with lowered apparent activation energy (Ea) in comparison to milled MgH2. The mechanism of desorption changes from Avrami–Erofeev n = 3 for as received MgH2 to Avrami–Erofeev n = 4 for composite materials. The change from 3 to 4 can be due to the modification of the nucleation process or a change in the dimensionality of the growth. Those high values of n disregard a diffusion control as a rate limiting step. It has been shown that there is a synergistic effect on the enhanced hydrogen storage performance of chemical reaction and structural changes caused by ball milling. This can be used as a starting point for synthesis of innovative hydrogen storage materials.

AB  - Metal and complex light hydrides are the best fitted materials for hydrogen storage within the concept of hydrogen based economy [1]. They meet the basic application requirements: low-cost, safety and they are environmentally friendly. Beside their benefits, as relatively stable compounds, these materials exhibit also some undesirable properties like sluggish kinetics and high temperature of hydrogen desorption. LiAlH4 has emerged as a potential material for solid-state hydrogen storage because of its high hydrogen gravimetric capacity (10.5 wt%). It decomposes in three steps, according to the reactions [2]: 3LiAlH4 → Li3AlH6 + 2Al + H2                             (R1) Li3AlH6 → 3LiH + Al + 3/2H2               (R2) 3LiH+3Al → 3LiAl + 3/2H2                              (R3) The temperature of the first reaction is between 150-175°C, of the second between 180-220°C and the third between 400420°C. The first two reactions (R1 and R2) are very important from the hydrogen storage point of view: (i) both take place at a reasonable low temperatures and (ii) overall sum of theirs gravimetric hydrogen capacity is 7.8 wt.%, so the reactions (R1) and (R2) are accessible for practical hydrogen storage. However, the slow dehydrogenation kinetics and irreversibility under moderate condition hinder its imminent application.  Particle refinement and catalyst or additive introduction by mechanical milling led to the significant improvement of LiAlH4 hydrogen storage properties [2].  However, during the milling process, the temperature in the milling chamber can significantly increase reaching the temperature of R1 or even R2 leading to the degradation of hydride, change in the hydrogen desorption mechanism (figure 1) and decrease in the hydrogen storage capacity of material [3]. So, in this work the impact of metallic (V, Mn an Cr) and metal oxide (Fe2O3 and Nb2O5) additives on the LiAlH4 hydrogen desorption properties with the emphasis on the hydride degradation process during milling and a consequent hydrogen desorption reaction mechanism was studied. The aim was to improve the hydrogen desorption kinetics without hydrogen capacity deterioration.

AB  - Mechanical milling of pure lithium alanate (LiAlH4) was done with addition of 5 weigh percent of Fe2O3 using different milling time ranging from 1 to 15 minutes [1]. Mechanical milling of composites causes destabilization of LiAlH4 structure as it observed by XRD measurements. Particle size distribution results reveals that composite particle size decrease with milling time up to 3 minutes, and then increase almost to the original size, for 15 min sample. Mechanical mailing cause phase transformation from AlH4- to AlH63-. As a consequence of structural and chemical changes, desorption properties of composites are change kinetic of desorption is improved in comparison to unmilled LiAlH4. The shifting of hydrogen desorption temperature to lower temperatures is observed together with change from multi-step desorption to one-step hydrogen desorption is also observed. This caused decrease in activation energy of composites from Ea = 665 kJ/mol for unmilled LiAlH4, Ea = 279 kJ/mol for 3 min milled composite.

AB  - The influence of different milling conditions obtained using two high-energy mills on hydrogen desorption from MgH2-WO3 composites was investigated. The morphology, particle and crystallite size were studied as a function of milling speed, vial's volume, and ball-to-powder ratio. The vial's fill level, the number, and type of milling balls and additive's content kept constant. Changes in morphology and microstructure were correlated to desorption properties of materials. Higher milling speed reduced particle size but, there is no significant crystallite size reduction. On the other hand, additive distribution is similar regardless of the energy input. It has been noticed that different energy input on milling blend, which is the result of combined effects of above-mentioned factors, reflects on desorption temperature but not on the kinetics of desorption. In fact, desorption mechanism changes from 2D to 3D growth with constant nucleation rate, despite obtained changes in microstructure or chemical composition of the material. © 2019 Hydrogen Energy Publications LLC

AB  - This review deals with the destabilization methods for improvement of storage properties of metal hydrides. Both theoretical and experimental approaches were used to point out the influence of various types of defects on structure and stability of hydrides. As a case study, Mg, and Ni based hydrides has been investigated. Theoretical studies, mainly carried out within various implementations of DFT, are a powerful tool to study mostly MgH 2 based materials. By providing an insight on metal-hydrogen bonding that governs both thermodynamics and hydrogen kinetics, they allow us to describe phenomena to which experimental methods have a limited access or do not have it at all: to follow the hydrogen sorption reaction on a specific metal surface and hydrogen induced phase transformations, to describe structure of phase boundaries or to explain the impact of defects or various additives on MgH 2 stability and hydrogen sorption kinetics. In several cases theoretical calculations reveal themselves as being able to predict new properties of materials, including the ways to modify Mg or MgH 2 that would lead to better characteristics in terms of hydrogen storage. The influence of ion irradiation and mechanical milling with and without additives has been discussed. Ion irradiation is the way to introduce a well-defined concentration of defects (Frankel pairs) at the surface and sub-surface layers of a material. Defects at the surface play the main role in sorption reaction since they enhance the dissociation of hydrogen. On the other hand, ball-milling introduce defects through the entire sample volume, refine the structure and thus decrease the path for hydrogen diffusion. Two Severe Plastic Deformation techniques were used to better understand the hydrogenation/dehydrogenation kinetics of Mg- and Mg 2 Ni-based alloys: Equal-Angular-Channel-Pressing and Fast-Forging. Successive ECAP passes leads to refinement of the microstructure of AZ31 ingots and to instalment therein of high densities of defects. Depending on mode, number and temperature of ECAP passes, the H-sorption kinetics have been improved satisfactorily without any additive for mass H-storage applications considering the relative speed of the shaping procedure. A qualitative understanding of the kinetic advanced principles has been built. Fast-Forging was used for a “quasi-instantaneous” synthesis of Mg/Mg 2 Ni-based composites. Hydrogenation of the as-received almost bi-phased materials remains rather slow as generally observed elsewhere, whatever are multiple and different techniques used to deliver the composite alloys. However, our preliminary results suggest that a synergic hydrogenation / dehydrogenation process should assist hydrogen transfers from Mg/Mg 2 Ni on one side to MgH 2 /Mg 2 NiH 4 on the other side via the rather stable a-Mg 2 NiH 0.3 , acting as in-situ catalyser. © 2019 Wiley-VCH Verlag GmbH & Co.

AB  - This review deals with the destabilization methods for improvement of storage properties of metal hydrides. Both theoretical and experimental approaches were used to point out the influence of various types of defects on structure and stability of hydrides. As a case study, Mg, and Ni based hydrides has been investigated. Theoretical studies, mainly carried out within various implementations of DFT, are a powerful tool to study mostly MgH 2 based materials. By providing an insight on metal-hydrogen bonding that governs both thermodynamics and hydrogen kinetics, they allow us to describe phenomena to which experimental methods have a limited access or do not have it at all: to follow the hydrogen sorption reaction on a specific metal surface and hydrogen induced phase transformations, to describe structure of phase boundaries or to explain the impact of defects or various additives on MgH 2 stability and hydrogen sorption kinetics. In several cases theoretical calculations reveal themselves as being able to predict new properties of materials, including the ways to modify Mg or MgH 2 that would lead to better characteristics in terms of hydrogen storage. The influence of ion irradiation and mechanical milling with and without additives has been discussed. Ion irradiation is the way to introduce a well-defined concentration of defects (Frankel pairs) at the surface and sub-surface layers of a material. Defects at the surface play the main role in sorption reaction since they enhance the dissociation of hydrogen. On the other hand, ball-milling introduce defects through the entire sample volume, refine the structure and thus decrease the path for hydrogen diffusion. Two Severe Plastic Deformation techniques were used to better understand the hydrogenation/dehydrogenation kinetics of Mg- and Mg 2 Ni-based alloys: Equal-Angular-Channel-Pressing and Fast-Forging. Successive ECAP passes leads to refinement of the microstructure of AZ31 ingots and to instalment therein of high densities of defects. Depending on mode, number and temperature of ECAP passes, the H-sorption kinetics have been improved satisfactorily without any additive for mass H-storage applications considering the relative speed of the shaping procedure. A qualitative understanding of the kinetic advanced principles has been built. Fast-Forging was used for a “quasi-instantaneous” synthesis of Mg/Mg 2 Ni-based composites. Hydrogenation of the as-received almost bi-phased materials remains rather slow as generally observed elsewhere, whatever are multiple and different techniques used to deliver the composite alloys. However, our preliminary results suggest that a synergic hydrogenation / dehydrogenation process should assist hydrogen transfers from Mg/Mg 2 Ni on one side to MgH 2 /Mg 2 NiH 4 on the other side via the rather stable a-Mg 2 NiH 0.3 , acting as in-situ catalyser. © 2019 Wiley-VCH Verlag GmbH & Co.

AB  - Magnesium hydride (MgH2 ) is one of the most favorable hydrogen storage materials because it is directly formed from the reaction of Mg metal with gaseous hydrogen while reaching a high mass capacity (7.6 wt %). However, the sorption reaction is too slow for practical use and needs higher temperature than 300 °C for hydrogen sorption reactions. The hydrogen storage properties can be tailored by addition of small amount of transition metal oxides (TiO2,VO2 ). In order to understand the processes that occurred during sorption reaction we have used both theoretical and experimental approach to study reaction mechanism in powder and thin films materials. Processes taking place during hydrogen desorption from Mg/MgH2 thin films upon modification either by TiO2 capped layer or by ion irradiation were also investigated. Irradiation was used to produce controlled point defects quantity with well-defined depth distribution. It was shown that the size, shape, and concentration of Mg nuclei formed during hydrogen desorption from MgH2 thin films depend on the characteristics and distribution of the induced defects. Addition of VO2 to powder milling bland dramatically improves the kinetics of sorption reaction, It is worth to notice that the full charge/discharge is achieved at relatively low temperatures.

AB  - Magnesium hydride, as hydrogen storage material, meets the requirements such as high gravimetric hydrogen capacity (7,6 wt%), low cost and weight, abundance and H2 absorption/desorption cycling possibility. Given that the oxide additives show the good impact on desorption properties, mechanical milling of MgH2 with addition of 5, 10 and 15% wt. WO3 was performed. The microstructure and morphology of composites were analysed by XRD, PSD and SEM and correlated to hydrogen desorption properties which have been investigated by DSC. The results have shown that WO3 has a positive effect on the desorption kinetics as well as on the change of the desorption mechanism.
