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

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 Co89.8Ni10.2P11.7/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. Fully interacting: A Co89.8Ni10.2P11.7/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.
