▎ 摘　　要

Developing highly efficient and stable noble-metal-free catalysts toward catalytic hydrolysis of ammonia borane (AB) for hydrogen storage is highly desirable, but still remains challenging. We report a simple and insitu co-reduction approach to synthesize bimetallic NiCoP nanoparticles (NPs) supported on reduced graphene oxide (rGO). Thanks to the strong electronic interaction between Ni, Co, and P, the as-synthesized Co89.8Ni10.2P11.7/rGO catalyst exhibits superior catalytic performance towards hydrolysis of AB, with the turnover frequency value (TOF) of 18.6min(-1), which is about 2.5 times higher than that of NiCo/rGO.
