| 摘 要： | 运用磁控溅射技术在浸渍－提拉法制得的TiO2薄膜上溅射三氧化钨层得到光催化薄膜。采用SEM、XRD、AES、UV－vis漫反射光谱等方法表征催化剂薄膜的厚度、晶相结构、化学元素组成及光吸收性能。以甲基橙的光催化降解为反应模型，高压汞灯为光源，溅射有三氧化钨薄膜的光催化活性低于纯TiO2薄膜；滤过紫外光后，溅射有三化钨的薄膜光催化活性明显高于纯TiO2薄膜。本实验提供了一种制备高可见光活性的TiO2薄膜的方法。 |
| 关 键 词： | 制备 光催化性能 薄膜 可见光活性 二氧化钛 磁控溅射 氧化钨 |

| Abstract: | TiO2 films made from dip-coating system were modified by the magnetr on sputtering of WO3.The thickness, phase, chemical composition and the optical absorption of the f ilms were characterizedby means of SEM, XRD, AES, UV-vis reflectance spectra techniques. With irradi ation of high-pressure mercury lamp, the photo-catalytic behavior of film magnetron sputter ed with WO3 is weakenedin the degradation of orange methyl, while with the addition of UV light filte r, the photo-catalytic behavior is enhanced. A preparation method of TiO2 film with high visible ligh t activity is proposed. |
| Keywords: | film visible-light activity TiO2 magnetron sputtering WO3 |
