研究了负载Sm ~（3+）的CeO_2/RuO_2光催化分解水为氢和氧的性能。纯CeO 2催化剂的活性很低，而固相反应法合成的具有非均相掺杂结构的Sm ~（3+）掺杂CeO 2催化剂的活性很高，而共沉淀法合成的具有均相掺杂结构的Sm ~（3+）掺杂CeO 2催化剂的活性很低。本文研究了光催化活性与表面掺杂结构的关系。
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.
