| 摘 要： | 以具有多孔结构的天然斜发沸石为载体, FeCl3和TiCl4为前驱物制备铁离子掺杂TiO2光催化剂. 分别在紫外光和太阳光照射下, 研究了Fe-TiO2, TiO2/沸石和Fe-TiO2/沸石对甲基橙溶液(MO)的光催化分解过程, 并通过XRD, AFM, FTIR和吸收光谱等手段, 探讨了Fe和沸石对TiO2的光催化活性的影响. 结果表明, 适当浓度的Fe不仅可以提高TiO2的光催化效率, 而且能够拓展TiO2的吸收波长范围至可见光区. 而沸石的引入不仅提高了光催化剂的效率, 而且也增强了光催化剂的抗失活性能.

| Abstract: | Iron ion doped TiO_2 photocatalysts were prepared from FeCl_3 and TiCl_4.The photocatalytic degradation of Methyl Orange(MO) in the systems of Fe-TiO_2,TiO_2/zeolite and Fe-TiO_2/zeolite photocatalysts under both solar and UV light irradiation was investigated in order to evaluate and distinguish various effects of the Fe and natural zeolite on TiO_2 photocatalytic activity.The photocatalysts were characterized by XRD,AFM,FTIR and spectrophotometer.The results show that the addition of Fe enhances the photoactivity of TiO_2 and shifts the excited wavelength of TiO_2 to visible light regions.Moreover,the loading effects of natural zeolite increase both the activity and the anti-death ability of the photocatalysts. |
