Synthesis of Pt–Ni/graphenevia in situreduction and its enhanced catalyst activity for methanol oxidation

Abstract

A simple in situ reduction approach was used to obtain Pt₃Ni/reduced graphene oxide (rGO) with dominant {111} facets. The catalytic activity of Pt–Ni/rGO toward methanol electro-oxidation was studied by performing cyclic voltammetry. The Pt₃Ni/rGO nanocatalysts exhibited improved catalytic activity and durability.
