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. (C) 2010 Sheng Jun Li.
