Synthesis of dendritic Pt–Ni–P alloy nanoparticles with enhanced electrocatalytic properties

Abstract

Dendritic Pt–Ni–P alloy NPs with different chemical compositions were successfully synthesized via a facile wet-chemical route. Owing to the unique dendritic nanostructures and synergistic electronic effects of P, Ni, and Pt atoms, the as-prepared dendritic Pt–Ni–P alloy NPs exhibit a higher electrocatalytic activity than dendritic Pt–Ni alloy NPs and commercial Pt/C.
