The hydrolysis of MgH2 delivers high hydrogen capacity (15.2 wt%), which is very attractive for real-time hydrogen supply. However, the formation of a surface passivation Mg(OH)2 layer and the large excess of H2O required to ensure complete hydrolysis are two key challenges for the MgH2 hydrolysis systems. Now, a low-cost method is reported to synt...

AB2-type Ti-based alloys with Laves phase have advantages over other kinds of hydrogen storage intermetallics in terms of hydrogen sorption kinetics, capacity, and reversibility. In this work, Ti–Zr–Cr-based alloys with progressive Mn, Ni, and V substitutions are developed for reversible hydrogen storage under ambient conditions (1–40 atm, 273–333...

... Main issue that hinders further implementation of hydrogen fuel cell technologies is in the need of a compact, safe, and efficient hydrogen storage. Along with various methods of reversible hydrogen storage based on physical processes (compression, liquefaction) and the use of hydrogen storage materials (high-surface area adsorbents, hydrides, liquid organic hydrogen carriers, etc.) [6], special attention has been recently paid to on-site (or on-board) hydrogen generation by the hydrolysis of various lightweight materials like ammonia borane [7], sodium borohydride [8], aluminium [9], magnesium and magnesium alloys [10][11][12][13][14][15], magnesium hydride [11,[16][17][18][19], and so on. These materials can undergo hydrolysis at near-ambient conditions, in alkaline, acidic, or neutral medium, frequently, at presence of a catalyst. ...
... These shapes are related to the occurrence or not, respectively, of phase separation between a low hydrogen content solid solution and high hydrogen content hydride. This phase separation might be understood as a hydrogen miscibility gap in the C14 Laves phase alloy, as discussed in detail by Ponsoni et al. 17 PCT curves with a well-dened plateau pressure were reported for the Laves phase alloys TiZrCrMnFeNi, 5 28 On the other hand, the absence of a well-dened plateau pressure suggests hydrogen absorption by interstitial solid solution, as considered in the development of the PCT-C14 model. This behavior was reported for the TiZrNbFeNi, 6 Cr u Fe v Mn w Ti x V y Zr z , 8 ZrTiVNiCrFe, 24 and Ti 0.5 Zr 0.5 (V 0.5 Ni 1.1 Mn 0.2 Fe 0.2 ) 2 (ref. ...
