| 摘 要： | 采用溶胶-凝胶法制备了以玻璃为基底具有高光催化活性,表面均匀、透明、无裂纹的纳米TiO2薄膜.研究了反应物配比对薄膜表面形貌、透光率和光催化活性的影响,确定了最佳反应物配比.采用扣除背景干扰的方法,利用甲基橙的降解率对TiO2薄膜的光催化性能进行了评价,对其透光率、光催化活性以及物相形貌进行了表征.结果表明,在最佳反应物配比条件下,所制备的TiO2薄膜表面光滑平整,粒径为纳米级且分布均匀,具有80%高透光率和99%高光催化活性. |

| Abstract: | The crack-free,well proportioned,transparent and high photocatalytic activity TiO2 film was prepared on soda-lime glass substrates by sol-gel method.Effect of the rations of reactants on appearance,light transmittance,photo-catalytic activity were studied.The best prepared conditions was defined.Through excluding the background interference,photo-catalytic activity of the thin films was evaluated by the degrading rate of methyl orange.The appearance,light transmittance and photo-catalytic activity of the fi... |
| Keywords: | nano-TiO_2 film ration of reactants appearance transmittance photo-catalytic activity |
