Highly efficient dehydrogenation of hydrazine over graphene supported flower-like Ni–Pt nanoclusters at room temperature

Abstract

Flower-like Ni–Pt nanoclusters assembled on graphene have been facilely synthesized by a co-reduction route. Thanks to the unique structure and strong interaction with graphene, the as-synthesized Ni₃Pt₇/graphene nanoclusters exhibit 100% hydrogen selectivity and exceedingly high activity toward hydrogen generation from alkaline solution of hydrazine at room temperature.
