“…In particular, noble metal-based catalysts such as Fe@Pt core-shell nanoparticles [9], Au@Co core-shell nanoparticles [8], Pt x Ni 1−x nanoparticles [15,16], ruthenium supported on carbon [17], water-soluble poly (4-styrenesulfonic acid-co-maleic acid) stabilized ruthenium(0) and palladium(0) nanoclusters [18], zeolite confined palladium(0) nanoclusters [5], zeolite confined rhodium(0) nanoclusters [6], zeolite framework stabilized rhodium(0) nanoclusters [19], water soluble lauratestabilized ruthenium(0) nanoclusters [20] have exhibited very high catalytic activity for hydrolysis of NH 3 BH 3 . Non-noble metal catalysts such as Co nanoparticles [21], Ni nanoparticles [7], intrazeolite cobalt(0) nanoclusters [2], cobalt chloride CoCl 2 [3], nanoparticle-assembled Co-B thin film [22], electroplated Co-P [1], cobalt-molybdenum-boron/nickel foam [23], water-soluble polymer-stabilized cobalt(0) nanoclusters [24], poly (N-vinyl-2-pyrrolidone) (PVP) stabilized nickel [25], nanosized Co-and Ni-based catalysts [26], zeolite confined copper(0) nanoclusters [27], hollow Ni-SiO 2 nanosphere [28], Fe-Ni alloy [29] have also shown high H 2 generation kinetics from hydrolysis of NH 3 BH 3 .…”
