In Situ Synthesis of NiCoP Nanoparticles Supported on Reduced Graphene Oxide for the Catalytic Hydrolysis of Ammonia Borane

Graphical Fully interacting : A Co 89.8 Ni 10.2 P 11.7 /reduced graphene oxide (rGO) catalyst was successfully synthesized by a simple in situ co-reduction method. The strong electronic interaction between Ni, Co, and P means that this species is an efficient catalyst toward hydrolysis of ammonia borane at room temperature, and exibits remarkable catalytic activity, which is 2.5 times higher than that of NiCo/rGO. 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 in situ 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 Co 89.8 Ni 10.2 P 11.7 /rGO catalyst exhibits superior catalytic performance towards hydrolysis of AB, with the turnover frequency value (TOF) of 18.6 min −1 , which is about 2.5 times higher than that of NiCo/rGO.
