摘要：

The impedance and photoelectrochemical properties of titanium oxide film formed by direct thermally oxidation of titanium were investigated by electrochemical impedance spectroscopy, photocurrent response etc. The results showed that the charge transfer resistance of interfacial decreased, while photocurrent increased gradually and the photoelectrocatalytic degradation rate of aniline increased with increasing the oxidation temperature. The photoelectrochemical performance of TiO2 electrode decreased sharply when the oxidation temperature was higher than 600 degreesC. There had good correlation between the structure of catalyst, charge transfer resistance of interfacial, photocurrent and photoelectrocatalytic degradation rate of aniline.
