| 摘 要： | 以溶胶一凝胶法制备了钇（Y）掺杂的TiO2，采用SEM、EDS、BET、XRD等测试手段对其进行了表征．XRD分析结果表明钇掺杂的TiO2具有锐钛矿型结构；SEM观察发现该催化剂表面有大量孔，平均粒径为10～20nm；EDS测试表明Y在TiO2中分布均匀；BET测试结果表明掺杂钇后，催化剂比表面积由原来的49．03m^2／g增加到99．43m^2／g；通过对甲基橙的光催化降解测试证明Y掺杂的TiO2的催化效率比纯TiO2有很大提高，90min时降解率达到85％，比纯TiO2降解效率提高40％．实验还表明Y掺杂的TiO2对可见光的响应活性比纯TiO2有一定提高．

| Abstract: | TiO2 doped with Y was prepared by sol-gel method using tetrabutyl titanate as raw material and characterized by SEM,EDS,BET and XRD and are proved to be a size of 10-20 nm nanoparticles. SEM observation found with lots of holes on the surface of catalyst. EDS test shows that Y distributed evenly in the TiOz ;BET test showed that the specific surface area increased from 49.03 m2/g of pure TiO2 to 99.43 m2/g of TiO2 （Y）. XRD characterize for pure anatase. The photocatalytic degradation experiments prove that the cata cy of TiO1 doped with Y for methyl radiation of UV. Experiments also higher than that of the pure TiO2. orange is 40% higher than the pure TiO2 lytic efficien- after 90 min show that TiO2 doped Y responsing to visible light is |
