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  - 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.
