摘　　要：TiO2 colloid was prepared by the sol-gel method and was bladed on transparent conduction glass to made nanoporous electrode. The impedance performance of TiO2 electrode was studied at various bias potential.A simplified equivalent circuit was proposed to investigate the charge transport impedance of TiO2 film and good fitting results were obtained.TiO2 colloid was prepared by the sol-gel method and was bladed on transparent conduction glass to made nanoporous electrode.
