| 摘 要： | 采用溶胶-凝胶法制备了La^3＋／TiO2光催化剂，研究了该催化剂对亚甲基蓝的光催化降解效果。结果表明，La^3＋掺杂量（摩尔分数）2．8％、催化剂用量1．2g／L、体系pH值为11时，12mg／L亚甲基蓝溶液经2h光催化降解，其降解率可达99．1％。与纯TiO2相比，La^3＋/TiO2光催化剂显示出良好的光催化活性。

| Abstract: | La3 /TiO2 photocatalyst was prepared by the sol-gel method.The photocatalytic degradation of MB was studied.The results show that La3 doped TiO2 exhibits greater photocatalytic activity than pure TiO2,When the optimum dosis of La3 doped is 2.8%,the optimum dosis of catalyst is 1.2 g/L,pH is 11,and the photocatalytic degradation of MB arrives 99.1%. |
