题目:溶胶凝胶法制备Fe2O3-TiO2表面膜及其性能研究
摘要
TiO2薄膜是众多氧化物半导体薄膜中研究最为广泛的一种材料,其表面的超亲水性和自清洁效应开辟了光催化功能薄膜材料新的研究领域。
本文以钛酸丁酯为钛源,通过溶胶-凝胶法制备了可与水以任意比例混合,并可直接涂覆使用的掺铁的TiO2溶胶。%的TiO2的光催化性;%的TiO2的亲水性;%的TiO2薄膜的晶相结构;通过光学电镜测试研究了掺铁前后TiO2薄膜的表面形貌特征。
研究结果表明:%(摩尔比)的TiO2镀膜层数为3层、,温度为500℃时,所制备出的薄膜致密均匀,光滑透明且不开裂;紫外光照后,薄膜具有超亲水性和较强的光催化活性。

Abstract
TiO2 film is many oxide semiconductor in film studies the most extensive a kind of material, the surface of super hydrophilic and clean effect since opened up a photocatalytic function film material new research area.
In this paper, the titanium butyl acrylate acid for titanium source, through sol-gel method with water in any mixing ratio, and can be directly coating of the mixed use iron TiO2 sol. Through the degradation of methyl orange with research content is % of the iron of TiO2 photocatalysis sex; Through the drop in glass surface drops of water in the water and the diameter of the contact Angle iron content is % with research of the hydrophilic TiO2; By means of the diffraction mixed iron content is % of TiO2 film crystal phase structure; Through the scanning electron microscopy test study of the effects of TiO2 film iron and surface morphology characteristics
The results show that: the iron ion doping concentration of % (Moore than ) of the mole ratio of TiO2 film coating layer 3 layer, calcining time of and annealing temperature of 500℃, the preparation of the film even, smooth transparent and dense cracks; Ultraviolet light, the film has super hydrophilic and strong light catalytic activity.
Key words: Nano TiO2 film; Sol-gel method; Self Cleaning
