摘要：

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. (C) 2014 Elsevier B.V. All rights reserved.
