| Abstract: | Au-Pt alloy nanoparticles were synthesized by chemical co-reduction method,KBH4 as reducing agent and PVP as protecting agent.Nanoparticles were characterized by UV-vis,TEM and XRD.Electrocatalytic activity of Au-Pt/C alloy catalysts toward methanol oxidation was studied by cyclic voltammetry(CV).It was found that the catalytic activity of Au-Pt/C catalysts toward methanol is significantly higher than that of Pt/C catalyst,which is related to the molar ratio of Au and Pt. |
