PdxAgy alloy nanoparticles supported on reduced graphene oxide as efficient electrocatalyst for ethanol oxidation in alkaline medium

Well-dispersed PdxAgy alloy nanoparticles supported on reduced graphene oxide (RGO) sheets (PdxAgy/RGO) are successfully synthesized by in situ reduction precipitation using hydrothermal synthesis method. The as-prepared Pd1Ag1/RGO nanocomposite exhibits higher electrocatalytic activities than the commercial Pd/C catalyst for ethanol electro-oxidation in alkaline medium.
