Synthesis and electrocatalytic activity of Au/Pt bimetallic nanodendrites for ethanol oxidation in alkaline medium

► Bimetallic Au/Pt nanodendrites were successfully prepared by seeded growth method. ► Pt/Au catalysts show high activity for ethanol oxidation in alkaline condition. ► The finding will be avail to develop advanced catalysts in direct ethanol fuel cell. ► First report about Pt/Au nanostructures as catalysts for ethanol electro-oxidation.
