“…In this review, we focus on the recent progress in the dehydrogenation and rehydrogenation reactions of M(BH 4 ) n at controlled temperature and hydrogen pressure. Some several excellent reviews on M(BH 4 ) n are also available [2,[12][13][14][15][16][17][18].…”

Abstract:The prerequisite for widespread use of hydrogen as an energy carrier is the development of new materials that can safely store it at high gravimetric and volumetric densities. Metal borohydrides M(BH 4 ) n (n is the valence of metal M), in particular, have high hydrogen density, and are therefore regarded as one such potential hydrogen storage material. For fuel cell vehicles, the goal for on-board storage systems is to achieve reversible store at high density but moderate temperature and hydrogen pressure. To this end, a large amount of effort has been devoted to improvements in their thermodynamic and kinetic aspects. This review provides an overview of recent research activity on various M(BH 4 ) n , with a focus on the fundamental dehydrogenation and rehydrogenation properties and on providing guidance for material design in terms of tailoring thermodynamics and promoting kinetics for hydrogen storage.

“…Hydrogen is a promising alternative energy carrier that has been highly regarded because of its prominent advantages such as high energy density (142 MJ/kg [1]), great variety of potential sources, light weight, and environmental friendliness. Besides the application of hydrogen energy, many kinds of hydrogen storage materials have been studied in the past decades, such as lithium compounds [2,3], ammonia borane [4,5], as well as the hydrides of light metals [6,7].…”

We report a study on the desorption properties, crystallography and chemical state of MgH 2 and 1 mol% Nb 2 O 5 ball-milled composites. Desorption temperatures of the composites decreased with increase of ball-milling time. Size of MgH 2 crystallites decreased during ball-milling. Reduction of Nb 2 O 5 after ball-milling was confirmed by tracing the chemical state of Nb and was further supported by TEM observation. The reduced phases may act as more effective catalysts improving the desorption properties.

“…Compared to the gas-and/or liquid-state hydrogen storage, the storage of hydrogen in solid state based on the physical or chemical interaction between hydrogen and hydrogen storage materials usually has a higher hydrogen density. Among the developed hydrogen storage materials, the metal aluminum hydrides such as LiAlH 4 , NaAlH 4 and Mg(AlH 4 ) 2 are some of the most promising candidates for the on-board hydrogen storage owing to their high hydrogen capacity [1][2][3][4][5][6] . For example, Liu et al found that the Ti-doped LiAlH 4 can release 7 wt.% of hydrogen commencing at temperature as low as 80 °C, and that the dehydrogenated product can be re-hydrogenated almost completely under 100 bar of hydrogen and room temperature by employing liquid Me 2 O as a solvent 3 .…”

Thermolysis behavior of the Li-Sr-Al-N-H hydrogen storage system prepared by ball milling of Sr 2 AlH 7 + LiNH 2 mixture was investigated in this paper. The results show that thermal decomposition of the Li-Sr-Al-N-H system proceeds mainly in two steps with only hydrogen desorption. The thermal stability of this system is lowered as compared to the individual starting material, resulting in the hydrogen desorption initiating from about 125 °C. In addition, about 0.91 and 1.53 wt.% of hydrogen can be isothermally desorbed within 180 min at 180 and 330 °C, respectively. The decreased thermal stability of the Li-Sr-Al-N-H system might be attributed to the chemical reactions between the starting materials during the heating process with the formation of LiSrH 3 and N-containing amorphous phases.
