High-extent dehydrogenation of hydrazine borane N2H4BH3 by hydrolysis of BH3 and decomposition of N2H4

Hydrazine borane N2H4BH3 (HB, 15.4 wt% H) is a promising chemical hydrogen storage material. Herein, we report high-extent dehydrogenation of HB (i.e. hydrolysis of the group BH3 and decomposition of the moiety N2H4) in the presence of nickel-platinum nanoparticles (NPs) at 50 degrees C. Using Ni0.89Pt0.11 NPs, 5.79 +/- 0.05 equiv. H-2 + N-2 per HB can be released, corresponding to H-2 selectivity as high as 93 +/- 1%.
