Highly efficient hydrogen generation from hydrous hydrazine using a reduced graphene oxide-supported NiPtP nanoparticle catalyst

Ultrafine NiPtP nanoparticles (NPs) assembled on reduced graphene oxide (rGO) have been synthesized by a co-reduction route using sodium hypophosphite (NaH 2 PO 2 ) as the source of the nonmetallic P. The well-dispersed ultrafine NiPtP NPs with a diameter about 2 nm can be readily obtained. It is found that these catalysts demonstrate high selectivity and excellent catalytic activity for the decomposition of N 2 H 4 ·H 2 O at mild temperature. The enhanced catalytic performance can be attributed to synergistic effect of P-doping and strong high selectivity interaction with graphene support.
