摘　　要：以钛酸四丁酯为主要原料,采用溶胶凝胶法制备了钇掺杂纳米二氧化钛(TiO2)光催化剂,通过X射线光电子能谱分析(XPS),X射线衍射分析(XRD)方法对其进行表征;并以甲基橙水溶液降解率为光催化活性评价依据,结果显示钇掺杂能够提高二氧化钛光催化性能.The titanium dioxide（TiO2） nanoparicles doped with Yttrium was prepared by sol-gel method using etrabutyl titanate（TEOT） as one of the primary raw materials.The titania catalysts were characterized with XPS,XRD.The photocatalytic properties of Yttrium-doped TiO2 nanoparicles were estimated by decoloration of methyl orange.The results indicated that doping of Yttrium improved the photocatalytic property of TiO2 nanoparicles effectively.
