| 摘 要： | 利用静电自组装工艺在石英衬底上制备了结构有序的TiO2／PSS纳米复合膜，并采用UV-Vis-NIR分光光度计、原子力显微镜(AFM)对复合膜的结构与光催化性能进行了深入的研究。结果表明：有序多孔TiO2颗粒膜具有良好的光催化性能，能够在短时间内降解掉复合膜中有机成分，烧结处理薄膜的光催化性能明显优于紫外照射处理的样品。

| Abstract: | Ordered-structure multilayer thin films were prepared on quartz substrates by the electrostatic self-assembly method. The UV-Vis-NIR spectrophotometer and the atomic force microscope (AFM) were used to characterize the films. The results indicated that order structure nanoporous TiO2 thin films showed high photocatalytic activity, and that the photocatalytic activity of heat-treated thin film was higher than that of UV irradiated film. |
