利用液相沉积(LPD)法在ITO表面制备TiO2薄膜。光电流和交流阻抗（EIS）测试表明，这种TiO2/ITO液相沉积膜具有良好的光电性能，对紫外光产生灵敏、快速的电流响应，在此膜电极上通过施加一定的阳极偏压可有效分离光生电子-空穴对。将TiO2/ITO膜用于4-氨基安替比林的光电催化降解研究，与其他方法相比，利用此液相沉积膜电极的光电催化技术对于4-氨基安替比林的降解具有明显的协同效果，适合于该污染物的降解处理。当外加阳极偏压为+0.8 V，支持电解质Na2SO4浓度为0.1 mol/L，溶液pH为2.0时，0.1 mmol/L 4-氨基安替比林120 min的光电催化降解效率最高可达95%。

A thin layer of TiO2 film was deposited on ITO surface via the liquid phase deposition (LPD) process. The photocurrent and electrochemical impedance spectroscopy (EIS) measurements indicated that the as-prepared LPD TiO2/ITO film had an excellent photoelectrochemical performance, which showed a sensitive and rapid response to the UV irradiation. The photogenerated electron-hole pairs could be effectively separated by applying an external bias to the TiO2 film electrode. The LPD TiO2/ITO film was employed to study the photoelectrocatalytic (PEC) degradation of 4-aminoantipyrine. Compared with other techniques, the PEC technique based on such a LPD film electrode had a synergetic effect for 4-aminoantipyrine degradation. When the applied bias potential was+0.8 V and the supporting electrolyte concentration of Na2SO4 was 0.1 mol/L, the highest degradation efficiency within 120 min could reach 95%for 0.1 mmol/L 4-aminoantipyrine solution at pH 2.0.
