| 摘 要： | 利用溶胶-凝胶法和电场热处理工艺在玻璃表面制备出一层TiO2薄膜，采用DTA ，Raman光 谱，XRD和AFM等测试手段分析了TiO2薄膜在电场热处理过程中的晶化行为.然后 在理论上 分析了外电场对TiO2薄膜热处理过程的影响，提出了通过引入外电场促进TiO2薄膜从无 定形到锐钛矿的相转变的方法.通过甲基橙水溶液的光催化降解实验表明：在520℃电场热处 理条件下的TiO2薄膜的光催化效率高于未引入电场热处理的TiO2薄 膜.

| Abstract: | TiO2 thin films, which were heat-treated with an applied electric fie ld, were prepared by sol-gel method. The phase transformation behavior of TiO2 thin fil ms was studied by differential thermal analysis, atomic force microscopy and Ra man spectroscopy respectively. It was indicated that the phase transformation of non-crystalline to anatase could be accelerated with an applied electric field. Studies on photo-catalytic degradation showed that the photo-catalytic activity of TiO2 thin films in an applied electric field became higher. |
