Nanocatalysts for Hydrogen Generation from Ammonia Borane and Hydrazine Borane

Ammonia borane (denoted as AB, NH 3 BH 3 ) and hydrazine borane (denoted as HB, N 2 H 4 BH 3 ), having hydrogen content as high as 19.6 wt% and 15.4 wt%, respectively, have been considered as promising hydrogen storage materials. Particularly, the AB and HB hydrolytic dehydrogenation system can ideally release 7.8 wt% and 12.2 wt% hydrogen of the starting materials, respectively, showing their high potential for chemical hydrogen storage. A variety of nanocatalysts have been prepared for catalytic dehydrogenation from aqueous or methanolic solution of AB and HB. In this review, we survey the research progresses in nanocatalysts for hydrogen generation from the hydrolysis or methanolysis of NH 3 BH 3 and N 2 H 4 BH 3 .
