英文摘要	A sandwich-like CeO2/graphene nanocomposite (CeGS) with a uniform thin CeO2 crystalline film coating on reduced graphene oxide is presented. Large amounts of trivalent Ce and abundant oxygen vacancies (VO) were introduced onto the surface of CeGS. Due to the advantageous surficial crystal configuration, this CeGS displayed greatly enhanced catalytic activity and excellent durability for the oxygen reduction reaction (ORR). By DFT calculations, it was demonstrated that the Ce(III)-preponderant and V-O-containing surface benefited the intense chemical adsorption and activation of O-2 and optimized the intermediate reaction pathways.
