The electrochemical deposition of small amounts of Au and Pt on the surface of Ni nanoparticles supported on reduced graphene oxide and the electrooxidation of ethylene glycol on the AuPt-decorated Ni/reduced graphene oxide catalysts in alkaline solution are investigated. By selecting a short deposition time, a low concentration of metal precursors, and a positive applied potential, AuPt loadings of less than 1.0 mu g cm(-2) are obtained. Physical and electrochemical characterizations of AuPt/Ni/reduced graphene oxide reveal a much lower content of Pt relative to Au. However, AuPt/Ni/reduced graphene oxide behaves similar to monometallic Pt/reduced graphene oxide rather than to Au/reduced graphene oxide in ethylene glycol oxidation, while Ni/reduced graphene oxide and Pt-decorated Ni/reduced graphene oxide show no activity. Compared to Pt/reduced graphene oxide or Au/reduced graphene oxide, the peak intensities of AuPt/Ni/reduced graphene oxide are somewhat higher in terms of the glassy carbon substrate, but are significantly higher in terms of the AuPt mass loading. Another attractive feature of AuPt/Ni/reduced graphene oxide is low cost resulted from the low AuPt loading. The result of this study indicates that decorating the surface of non-noble metal with a small amount of two noble metals is an efficient method to fabricate highly active catalysts.
