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.

Key words: CeO2-TiO2 composite, nanocrystalline porous film electrode, photoelectrochemistry
