•Combining CeO2 and the promising graphene supporting material.•Pt/CeO2–graphene catalyst was prepared by one-step microwave assisted method.•Pt nanoparticles were better dispersed with smaller sizes.•The electrocatalytic activity and stability were significantly enhanced.
Pt/CeO2–graphene catalyst was rapidly prepared by an efficient one step microwave-assisted process using ethylene glycol (EG) as a green reducing agent. Platinum particles are better dispersed on CeO2–graphene composite support with smaller sizes. In electrochemical test, Pt/CeO2–graphene exhibited higher and more durable electrocatalytic activities for methanol oxidation than a comparative Pt/graphene catalyst. The enhanced performance might ascribe to the general promotion of COads electrooxidation reaction kinetics by the addition of CeO2.
