摘要：
Photocatalytic overall water splitting into hydrogen and oxygen on RuO2-loaded Sm3+-doped CeO2 was examined. Pure CeO2 showed a negligible small activity, however Sm3+ doped CeO2 with heterogeneous doping structure synthesized by solid state reaction exhibited an efficient activity, whereas Sm3+-doped CeO2 with homogeneous doping structure showed little activity when prepared by co-precipitation method. In this study, the relation between photocatalytic activity and surface doping structure was investigated.
