The invention discloses a method for synthesizing a PdPt/graphene nano electrical catalyst in one step by a microwave process, which comprises: dispersing graphene oxide in aqueous solution of quaternary ammonium salt surfactant through ultrasonic waves, adding solution of a soluble Pd II salt or PtII salt, fully and uniformly mixing, regulating the pH value of mixed solution, adding a reducer, uniformly mixing, reacting under radiation of microwaves to reduce palladium and platinum metal ions and graphene oxide, and cooling, washing and drying the reactants to obtain the PdPt/graphene nano electrical catalyst. The method has the characteristics of energy conservation, environmental protection, quickness, simple process and the like. The obtained PdPt/graphene nano electrical catalyst hasa high electric catalysis performance for the electrochemical oxidization of methanol.
