AB  - LiAlH4 is a promising material for hydrogen storage, having the theoretical gravimetric density of 10.6 wt% H2. In order to decrease the temperature where hydrogen is released, we investigated the catalytic influence of Fe2O3 on LiAlH4 dehydrogenation, as a model case for understanding the effects transition oxide additives have in the catalysis process. Quick mechanochemical synthesis of LiAlH4 + 5 wt% Fe2O3 led to the significant decrease of the hydrogen desorption temperature, and desorption of over 7 wt%H2 in the temperature range 143–154 °C. Density functional theory (DFT)-based calculations with Tran-Blaha modified Becke-Johnson functional (TBmBJ) address the electronic structure of LiAlH4 and Li3AlH6. 57Fe Mössbauer study shows the change in the oxidational state of iron during hydrogen desorption, while the 1H NMR study reveals the presence of paramagnetic species that affect relaxation. The electron transfer from hydrides is discussed as the proposed mechanism of destabilization of LiAlH4 + 5 wt% Fe2O3. © 2021 Hydrogen Energy Publications LLC

AB  - Metallic amidoboranes are widely investigated candidates for solid-state hydrogen storage, and much focus shifted recently toward bimetallic amidoboranes. Bimetallic amidoboranes are expected to introduce novel and enhanced physicochemical properties regarding storage and stability. However, these materials are still scarce and mostly grouped around magnesium- or aluminum-containing compounds. We present here a rapid and green mechanochemical solvent-free synthesis of two novel calcium-containing bimetallic amidoboranes, Li2Ca(NH2BH3)4 and Na2Ca(NH2BH3)4, from metal hydrides and ammonia borane. The insight into mechanochemical syntheses is provided by the in situ tandem synchrotron X-ray diffraction and thermal monitoring. The in situ data reveal how the choice of alkali metal hydride governs the course of reactions and their thermal profiles. In situ monitoring of thermal dehydrogenation of these materials is conducted by mass spectrometry and infrared spectroscopy, showing how the course of thermal decomposition varies depending on the structure of the amidoborane, resulting however in the same final products. These new hydrogen-rich bimetallic amidoboranes are structurally characterized by high-resolution powder X-ray diffraction, and they both show potential for hydrogen storage applications: high theoretical gravimetric capacities and low desorption temperatures of hydrogen without the significant presence of harmful gases. We also show how the choice of the milling reactor material can be decisive for the efficiency and overall success of the mechanochemical synthetic procedure, which may impact the design of milling syntheses for other thermally labile chemical systems. © 2021 American Chemical Society.

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  - The present work reports a new procedure for solid state synthesis of sodium amidoborane (NaAB) by mechanochemical (MC) reaction between as-received NaH and MC pretreated AB. Ball milling (BM) method was used for this purpose. First, pretreated AB was obtained by BM of as-received AB for 4.5 min. Second, powder of pretreated AB was mixed with as-received NaH and conducted to BM. Milling times were from 0 to 200 min: 5, 10, 30, 50, 100 and 200 min, respectively. By fixing the parameters of the milling conditions, only the influence of milling time on NaAB formation was followed. FTIR and XRD methods are used for analysis of powders after milling. We proved, by MC modification of pure AB, that the reaction rate between AB and NaH could be restricted to the interface between newly formed larger AB and small NaH particles. In such a way we obtained much better control of the reaction system with very accurate determination of reaction steps. Depending on the milling times, reaction process can be separated in three phases: i) 0–30 min phase - reactant and product are present; ii) 50–100 min phase - formed NaAB is almost without other pure; iii) 200 min phase - NaAB is totally decomposed. By this synthesis procedure we produced, for the first time, pure NaAB almost without any impurities. © 2019 Hydrogen Energy Publications LLC

AB  - For the first time, in situ monitoring of uninterrupted mechanochemical synthesis of two bimetallic amidoboranes, M2Mg(NH2BH3)(4) (M=Li, Na), by means of Raman spectroscopy, has been applied. This approach allowed real-time observation of key intermediate phases, and a straightforward follow-up of the reaction course. Detailed analysis of time-dependent spectra revealed a two-step mechanism through MNH2BH3 center dot NH3BH3 adducts as key intermediate phases which further reacted with MgH2, giving M2Mg(NH2BH3)(4) as final products. The intermediates partially take a competitive pathway toward the oligomeric M(BH3NH2BH2NH2BH3) phases. The crystal structure of the novel bimetallic amidoborane Li2Mg(NH2BH3)(4) was solved from high-resolution powder diffraction data and showed an analogous metal coordination to Na2Mg(NH2BH3)(4), but a significantly different crystal packing. Li2Mg(NH2BH3)(4) thermally dehydrogenates releasing highly pure H-2 in the amount of 7 wt.%, and at a lower temperature then its sodium analogue, making it significantly more viable for practical applications.

abstract = "For the first time, in situ monitoring of uninterrupted mechanochemical synthesis of two bimetallic amidoboranes, M2Mg(NH2BH3)(4) (M=Li, Na), by means of Raman spectroscopy, has been applied. This approach allowed real-time observation of key intermediate phases, and a straightforward follow-up of the reaction course. Detailed analysis of time-dependent spectra revealed a two-step mechanism through MNH2BH3 center dot NH3BH3 adducts as key intermediate phases which further reacted with MgH2, giving M2Mg(NH2BH3)(4) as final products. The intermediates partially take a competitive pathway toward the oligomeric M(BH3NH2BH2NH2BH3) phases. The crystal structure of the novel bimetallic amidoborane Li2Mg(NH2BH3)(4) was solved from high-resolution powder diffraction data and showed an analogous metal coordination to Na2Mg(NH2BH3)(4), but a significantly different crystal packing. Li2Mg(NH2BH3)(4) thermally dehydrogenates releasing highly pure H-2 in the amount of 7 wt.%, and at a lower temperature then its sodium analogue, making it significantly more viable for practical applications.",

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.

AB  - Desorption of hydrogen atoms from the (110) surface of rutile magnesium hydride (MgH2) was investigated using density functional theory (DFT) and pseudopotential method. System was represented by (110) (2x2) slab MgH2 supercell with 12 atomic layers along the z-axis. The H-desorption was modeled by the successive release of the four two-fold bonded H atoms from the (110) surface of MgH2. Dependence of the H-desorption energy on number and configuration of remaining surface hydrogen atoms has been determined. The features of the H atoms diffusion from the bulk towards the surface have been investigated, too. The results suggest that decrease in number of surface H atoms generally lowers the H-desorption energy in each desorption step and that both the H-H and the Mg-H interatomic interactions strongly influence the H-desorption process. The hydrogen vacancy formation energy in the first three sub-surface layers also exhibits a pronounced dependence on concentration. These findings lead to the conclusion that tendency of the MgH2 (110) surface to preserve a maximum possible surface H concentration in its most stable configuration is the limiting factor for the H-desorption kinetics. In principle, the obtained results allow us to determine preferred paths of surface and subsurface H-diffusion for a wide range of H concentrations and the principle features of the MgH2 dehydrogenation process, at least for the H-rich region. Being rather comprehensive, the approach is applicable for other metal hydrides, as well. Copyright (C) 2013, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd. All rights reserved.

AB  - Adsorption on activated carbon cloth is an efficient procedure for removing pollutants from wastewaters, because this material possesses large specific area and high adsorption capacity. Inthis study the activated carbon cloth was modified by mechanical milling in order to improve its sorption properties. The microstructure and morphology of the sample was investigated by XRD,PSD and SEM and surface chemistry was characterized by potentiometric titrations. The result showed that microstructure and morphology was drastically changed with milling: particle sizesreduction, agglomeration and the loss of fibrous structure occurred. These changes resulted in increase of the acidic and the base groups: the number of basic groups was increased by the factor of 11 while the number of acidic groups by the factor of 1.5.

AB  - The influence of structural changes caused by irradiation with different ions, their energies and fluences on sorption properties has been investigated. The irradiation has been done using B3+ and N3+ ions at 45 keV with ion fluence of 10(16) ion/cm(2) at the FAMA ion source at Vinca Institute of Nuclear Sciences in Belgrade. Morphology and microstructure of samples were analysed using XRD and particle size analysis, while estimation of penetration depth and deposition of defects were done by SRIM calculations. Hydrogen desorption properties and kinetics were evaluated from TPD measurements and numerical non-isothermal procedure. Results suggest that there are several mechanisms of desorption depending on defect concentration, their interaction and ordering. It has been also demonstrated that the changes in near-surface area play the crucial role in hydrogen desorption kinetics. It is confirmed that there is possibility to control the thermodynamic parameters of these systems by controlling vacancies depth profile and concentration.

AB  - The hydrogen desorption properties of MgH2-LiAlH4 composites obtained by mechanical milling for different milling times have been investigated by Thermal Desorption Spectroscopy (TDS) and correlated to the sample microstructure and morphology analysed by X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). The MgH2-LiAlH4 composites show improved hydrogen desorption properties in comparison with both as-received and ball-milled MgH2. Mixing of MgH2 with small amount of LiAlH4 (5 wt.%) using short mechanical milling (15 min) shifts, in fact, the hydrogen desorption peak to lower temperature than those observed with both as-received and milled MgH2 samples. Longer mixing times of the MgH2-LiAlH4 composites (30 and 60 mm) reduce the catalytic activity of the LiAlH4 additive as revealed by the shift of the hydrogen desorption peak to higher temperatures.

abstract = "The hydrogen desorption properties of MgH2-LiAlH4 composites obtained by mechanical milling for different milling times have been investigated by Thermal Desorption Spectroscopy (TDS) and correlated to the sample microstructure and morphology analysed by X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). The MgH2-LiAlH4 composites show improved hydrogen desorption properties in comparison with both as-received and ball-milled MgH2. Mixing of MgH2 with small amount of LiAlH4 (5 wt.%) using short mechanical milling (15 min) shifts, in fact, the hydrogen desorption peak to lower temperature than those observed with both as-received and milled MgH2 samples. Longer mixing times of the MgH2-LiAlH4 composites (30 and 60 mm) reduce the catalytic activity of the LiAlH4 additive as revealed by the shift of the hydrogen desorption peak to higher temperatures.

AB  - In attempt to improve desorption behaviour of MgH2, the influence of well-defined structural changes induced within a thin surface layer of MgH2 have been investigated. The defects were induced by 30 key C2+ ions irradiation using different fluencies ranging from 10(12)-10(16) ions/cm(2). The hydrogen desorption properties were investigated by thermal desorption spectroscopy analysis (TDS), while kinetics parameters were deduced using non-isothermal kinetic approach. The existence of multiple TDS peaks and different curve shapes indicate difference in desorption mechanism. To understand changes in the rate limiting step, shapes of all desorption peaks have been analyzed using different kinetic models. Regarding the irradiated sample, the function based on Avrami-Erofeev model with n = 4 gives the best fit over theta range from 0.3 to 0.8 while for untreated sample the best fit is obtained for Avrami-Erofeev model with n = 3. The change in mechanism can be attributed to the different way of nuclei growth. Copyright (C) 2013, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd. All rights reserved.

AB  - To improve hydrogen desorption properties of MgH2, mechanical milling of MgH2 with low concentration (2 and 5%) of NaNH2 has been performed. Pre-milling of MgH2 for 10 h has been done and then six samples have been synthesised with different milling times from 15 to 60 min. Microstructural characterisation has been performed using X-ray diffraction (XRD), scanning electron microscopy (SEM) and laser scattering measurements (PSD), and correlated to desorption properties examined using Differential Scanning Calorimetry (DSC) and Hydrogen Sorption Analyser (HSA). Thermal analysis shows that desorption temperatures are shifted towards lower values. It also highlights the significance of milling time and additive concentration on desorption behaviour.

AB  - This paper deals with non-isothermal kinetics models of hydrogen desorption from MgH2 altered by ion bombardment and stresses the importance of the MgH2 surface during its decomposition. In the case of argon-irradiated samples, where defects are induced in the near-surface region, the Avrami Erofeev mechanism with parameter n = 2 can be adopted while in the case of boron-irradiated samples, where defects are created deeper in the bulk, the desorption mechanism is the same with n = 3. The difference is possibly related to the concentration and good dispersion of defects in near-surface region in the samples. Copyright (C) 2012, Hydrogen Energy Publications, LLC.
