Abstract

Layer-by-layer films comprised of alternating graphene and Au@Pt nanostructures layers are readily produced by the three-step procedure involving the preparation of Au colloid, Au nanoparticles entering the layers of graphite, followed by Au@Pt nanostructures' formation by electrochemical methods on the graphene nanosheet. X-ray diffraction and Raman scattering showed the Au@Pt nanostructures/graphene was fabricated. Electrocatalytic properties of the resulting Au@Pt nanostructures/graphene electrode for methanol oxidation reaction were investigated. Compared with Au@Pt nanostructures/graphite, an appreciably improved electronic conductivity was observed for the Au@Pt nanostructures/graphene electrode.
