摘　　要：纳米ＴｉＯ２／Ｓｉ薄膜的制备与光催化性能的研究符小荣１，＊宋世庚１，２王学燕１谭辉１武光明１陶明德１（１中科院新疆物理所，乌鲁木齐８３００１１）（２中科院上海冶金所信息功能材料国家重点实验室，上海２０００５０）关键词ＴｉＯ２，光催化，薄膜，溶胶－凝胶...n this paper, TiO2/Si and TiO2/glass thin films with nanocrystalline have been prepared by the solgel processing of controlled Ti alkoxide hydrolysis. Their photocatalytic properties are also examined at the same time. The results indicate that by selecting substrates and annealing temperature the size of thin films can be controlled. The particle size effect and the thickness of films have effects on the photocatalytic activities of the thin films. Moreover, photocatalytic thin films can be reused.
