用溶胶-凝胶法制备了稀土Y^3＋掺杂TiO2，对其进行了XRD分析，以刚果红溶液为目标降解物研究了稀土Y^3＋掺杂TiO2的光催化性能。结果表明：同等实验条件下Y^3＋掺杂TiO2比纯TiO2的降解效果好。当稀土Y^3＋的掺杂量n（Y^3＋）：n（TiO2）=0．5％（摩尔比）、焙烧温度600℃、刚果红溶液初始浓度20mg／L、pH=3、催化剂用量为1．5g/L时，其光催化性能最佳。反应1h的降解率可达98．55％。

The titanium dioxide (TiO2) doped with Y^3+ was prepared by sol-gel and characterized by means of XRD. Photocatalysis performance of TiO2 doped with Y^3+ was studied targeting congo red solution. The results showed that under the same conditions of preparation, the degradation effect of TiO2 doped with Y^3+ was better than pure TiO2. When the molar ratio of Y^3+ and TiO2 was 0.5, the calcination temperature was 600 ~C, the initial concentration of congo red solution was 20 rag/L, the pH value was 3,and the dosage of TiO,. was 1.5 g/L, the photocatalytic properties of TiO2 was best. And the degradation rate reached 98.55% after degradation for 1 hour.
