摘　　要：使用TiCl4的前驱体溶液,采用阴极电沉积法在301不锈钢表面制备TiO2薄膜,并研究了电化学沉积过程的机理和工艺条件.应用X射线衍射(XRD)、热重-差热分析(TG-DTA)、傅立叶变换红外光谱(FTIR)等技术对TiO2沉积层的组成和结构进行了表征.用Tafel曲线评估了TiO2薄膜在模拟海水溶液中的电化学腐蚀行为,并以甲基橙为目标降解物研究了TiO2薄膜的光催化性能.TiO2 film is prepared by the method of cathodic electrodeposition in peroxotitanium solution of pure TiCl4, and the mechanism and process condition of electrochemical deposition are studied. The composition and structure of TiO2 deposit are characterized by X-ray diffraction （XRD）, thermogravimetric-differential thermal analysis （TG-DTA）, and Fourier transform infrared spectroscopy （FTIR）. Electrochemical corrosion behavior of TiO2 film on 301 stainless steel is measured in the solution of simulated seawater with Tafel technique. Moreover, photocatalytic performance of TiO2 film is evaluated through the photocatalytic decomposition of methyl orange.
