▎ 摘　　要

NOVELTY - A palladium-platinum/graphene nano electric catalyst is synthesized by dispersing ultrasonically graphene oxide in aqueous solution of quat. ammonium salt type surface active agent, adding soluble palladium (II) salt and platinum (II) salt solutions, mixing, adjusting the pH value of the mixed solution, adding reducing agent, reacting under microwave radiation, cooling, cleaning and drying. USE - Method of synthesizing palladium-platinum/graphene nano electric catalyst for electrochemical oxidation of methanol. ADVANTAGE - The method saves energy; is fast, simple and environment-friendly; and prepares product having high electrocatalysis performance.
