| 中文摘要 | 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.; TiO-2 thin films, which were heat-treated with an applied electric field, were prepared by sol-gel method. The phase transformation behavior of TiO-2 thin films was studied by differential thermal analysis, atomic force microscopy and Raman 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 TiO-2 thin films in an applied electric field became higher. |
