| 摘 要： | 用溶胶凝胶法制备了CeO2－TiO2复合纳米晶多孔膜电极，并用XRD及原子力显微镜（AFM）进行表征．通过光电化学研究，发现了CeO2-TiO2复合纳米晶电极光响应的p型和n型转换现象．结果表明，随着CeO2含量的不同及外电场的变化，CeO2－TiO2复合纳米晶电极可以呈现不同的光响应．

| Abstract: | The CeO2-TiO2 composite nanocrystalline porous film electrodes prepared by solgel method have been investigated by XRD, AFM and photoelectrochemcal methods. Thetranspositions of p-- and n--type photoresponses were observed on the composite film electrodes for the first time. It could be due to the competition between CeO2 and TiO2 photoresponses. This result Aught have a potential application in smart window and solar energyconversion. |
