Studies on metal oxide nanoparticles catalyzed sodium aluminum hydride

High capacity hydrogen storage: Basic aspects, new developments and milestones

“…The efficiency of the catalyst depends critically on how well it is dispersed throughout the system. Therefore, in solid-hydrogen reactions, it is desirable that the employed catalyst is in nanoform so as to increase catalyst-reactant contact area [26]. In the case of intermetallic hydrides the catalytic species present at the surface facilitates easy bond breaking/ formation and triggers rapid hydrogen absorption/desorption reaction.…”

Formation of Mg–Nb–O rock salt structures in a series of mechanochemically activated MgH2 + nNb2O5 (n = 0.083–1.50) mixtures

“…In the literature, additives from different classes such as, carbon, metals, metal oxides and metal halides were widely discussed [1e10]. Metal oxides, especially, have received considerable focus as additives for various metal hydride systems because the in-situ reduction of oxides can result in the formation of active surfaces for promoting metalehydrogen interaction [6,11,12]. In the literature, various surface features prompted by reduction of oxides, such as, low to high surface defect density [13], different surface chemical states [14], surface metal clusters [15], new secondary products and interfaces [16] etc, have been discussed.…”

The kinetics of lightweight solid-state hydrogen storage materials: A review

“…TiO 2 was determined to be the most effective catalyst [197,198]. The TiO 2 catalyst achieved great performance in NaAlH 4 with improved kinetics at low temperatures.…”
