摘　　要：ＴｉＯ２／Ｐｔ／ｇｌａｓ纳米薄膜的制备及对可溶性染料的光电催化降解符小荣＊张校刚＊＊宋世庚王学燕谭辉陶明德（中国科学院新疆物理研究所乌鲁木齐８３００１１，＊＊新疆大学化学系乌鲁木齐）关键词光催化，ＴｉＯ２，光电化学，薄膜，溶胶－凝胶法１９９６－０９－...TiO2/Pt/glass and TiO2/glass thin films in nanocrystalline have been prepared by solgel method and their structures and elctrochemically assisted photocatalysis have been examined. The results of electrochemically assisted photocatalytic degradation of dye solution by thin films indicate that the photocalytic activities of TiO2/Pt/glass thin films are higher than that of TiO2/glass thin films. Also, a more higher photocatalytic activity of TiO2/Pt/glass thin films can be achieved when an anodic bias is applied, and it increses with the increase of anodic bias. Forthermore, light showed effects on the photocatalytic activity of the thin film.
