| 摘 要： | 采用sol—gel法在载玻片表面制备了Ce，Cu，i．a，Ag掺杂的锐铁矿相TiO2薄膜，并通过SEM，XRD．FT—IR及UVVIS进行了表征，比较了薄膜的抗菌性能．UV—VIS研究表明，金属掺杂纳米TiO2薄膜在近紫外区吸光度有明显提高。抗菌实验表明掺Ag的TiO2薄膜抗菌效果最佳。

| Abstract: | Anatase metal （Ce, Cu, La, Ag）-doped TiO2 composite thin films deposited on glass substrates had been prepared by sol-gel technology, which were characterized by SEM, XRD, FT-IR and UV-Vis measurements. In addition, the antibacterial property of above thin films was compared. The results of UV-VIS showed that the films had the highest absorption, which led to higher photocatalytic degradation efficiency. The studies of antibacterial property of metal （Ce, Cu, La, Ag）-doping TiO2 photocatalytic thin films showed that Ag-doping TiO2 composite thin films had superior antibacterial property. |
