| 摘 要： | 以具有规则多孔结构的人造沸石为载体,以Nd(NO3)3和Ti(OBu)4为前驱体制备钕离子掺杂TiO2光催化剂.在紫外光的照射下,以甲基橙为光催化降解反应模型化合物,研究了TiO2、Nd-TiO2、TiO2/沸石、Nd-TiO2/沸石光催化剂的活性.通过FT-IR的表征,探讨了Nd和沸石对TiO2的光催化活性的影响.实验结果表明:掺杂钕离子能提高TiO2的光催化活性,催化剂用量为2 g/L,掺杂量为1.0%时,光催化活性最高;用人造沸石为载体所制得的TiO2光催化剂对甲基橙也具有较好的光催化降解效果.

| Abstract: | Nd ion doped TiO2 photocatalysts were prepared from Nd(NO3)3 and Ti(OBu)4,loaded by regular zeolite with many holes.Activities of TiO2,Nd-TiO2,TiO2/zeolite and Nd-TiO2/zeolite prepared photocatalysts were evaluated by decolorizing methyl orange(MO) as model compound to photocatalytic degradation under irradiation of high-pressure mercury lamp.The photocatalysts were characterized by FT-IR.The results show that the addition of Nd enhances the photoactivity of TiO2 and the optimum molar content of Nd may is 1.0% and the optimum dosage of photocatalyst is 2 g/L.Moreover the loading effects of artificial zeolite increases the activity of the photocatalysts. |
