摘　　要：采用溶胶—凝胶工艺制备了担载锐钛矿型ＴｉＯ２陶瓷膜，制备溶胶时所加ＣＨ３ＣＯＯＨ起控制Ｔｉ（ＯＣ４Ｈ９）４强烈水解的作用，加入量为：ＣＨ３ＣＯＯＨ／Ｔｉ（ＯＣ４Ｈ９）４＝８－１２，溶胶粘度４－６Ｐａ·ｓ，浸渍时间２０－２５ｓ，真空干燥，热处理温度４００℃，性能表征结果：三次涂膜孔径０．１７μｍ、孔径分布狭窄，耐酸碱性好，再生恢复率９７．１％。Anatase titania membranes with pore size(0.17μm)were prepared by sol-gel process. The synthesis condition and the factors affected sol-gel process, as manufacturing sol [CH 3COOH/Ti(OC 4H 9) 4 molar ratios] and preventing the membranes from craching, were discussed respectively. The membranes were characterized by XRD、pore size distribution and water flow.
