| 摘 要： | 稀土钐改性TiO2光催化性能有很大的争议，基于此采用溶胶-凝胶法制备了不同掺杂量和不同温度下煅烧的光催化剂，通过XRD和亚甲基蓝的降解实验，探讨了煅烧温度、空气流速、催化剂用量和掺杂量对亚甲基蓝的降解效果。结果表明：当煅烧温度为500℃，掺杂Sm^3＋为1．2％，空气流速达到1．3L／min，催化剂用量为1．5g／L时，催化性能达到最好。

| Abstract: | There are great disputes about the photocatalytic property of Sm^3＋ doped TiO2 powders. In this paper, TiO2 photocatalyst was made under the different conditions by sol-gel method. The calcine temperature,the velocity of air,the amount of catalyzer and the doped Sm^3＋ were investigate through XDR and MB degradation experiment. The results indicated that the better degradation effect was reached when 1.5 g/L TiO2 dopes with 1.2% （mol/L） Sm^3＋ was used under 500℃ and 1.3 L/min of air speed. |
