| 摘 要： | 采用溶胶-凝胶法制备了TiO2/Fe2O3异质结构的复合薄膜,运用XRD、AFM、紫外-可见光投射光谱等对薄膜的微结构、透光率及其光催化特性进行了表征,分析了薄膜结构对光催化性能的影响,并就可见光催化机理进行了探索.结果表明:具有异质结型的TiO2/TiO2/Fe2O3复合结构的薄膜在可见光区有较好的光催化效果,同时这一结构可有效地抑制电子-空穴复合.

| Abstract: | The heterojunction TiO2/Fe2O3 composite films were prepared by sol-gel method.Microstructure and transparent spectrum and photochemical catalysis nature of film were studied by X-ray diffraction(XRD),atomic force microscope(AFM) and UV-visible spectrophotometer.Efficiency of the film structure on the photochemical catalysis were analyzed,and mechanism of heterojunction was studied.The result indicats that,the heterojunction TiO2 /TiO2/Fe2O3 film has a good effect of photochemical catalysis respond in the area of visible light,and meanwhile,it can prevent the electron and hole compound. |
