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.
