N和Fe^(3+)共掺杂TiO_2薄膜的制备及亲水性能研究

Study on preparation and hydrophilicity of N and Fe^(3+) co-doped TiO_2 film

采用溶胶-凝胶法制备了N和Fe3+共掺杂的TiO2薄膜,研究了N,Fe3+不同掺杂比例、镀膜层数、热处理温度和光照时间等对TiO2薄膜亲水性能的影响.结果表明当掺杂物N和Fe3+的摩尔比为5.9∶1、镀膜层数为3层、热处理温度为550℃时,所制备的薄膜亲水性能最佳(接触角为2°).

N and Fe^3＋ co-doped TiO2 thin film were prepared by Sel-gel process. The influences of different N and Fe^3＋ ratio, film thickness, heat-treated temperature and sunlight irradiating time on the film hydrophilicity were studied. The result indicated that the hydrophilicity is the best （contact angle is 2°） as the mol ratio of N and Fe^3＋ is 5.9 ： 1, the thickness is 3 cycle coating and the heat-treated temperature is 550 ℃.
