Synthesis of Pt-Ni/graphene via in situ reduction and its enhanced catalyst activity for methanol oxidation

摘要

A simple in situ reduction approach was used to obtain Pt_3Ni/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 Pt_3Ni/rGO nanocatalysts exhibited improved catalytic activity and durability.
