| 摘 要： | 以钛酸四丁酯为原料,利用溶胶凝胶法制备了Cr/Ag共掺杂的TiO2纳米材料.采用XRD、SEM、EDS等测试分析技术对掺杂纳米TiO2粉体进行了表征;以甲基橙为降解物,在太阳光照射条件下研究了掺杂对光催化活性的影响.研究结果表明:掺杂后的纳米TiO2的光催化性能明显提高,优于纯TiO2.当共掺杂的比例为Cr 1.0%/Ag 0.5%时,样品的效果最佳,对甲基橙的3h降解率达到97.63%.

| Abstract: | The co-doped of Cr and Ag TiO2 was prepared by Sol-gel using Ti（OC4H9）4 as raw materials. The structure and morphology of TiO2 have been characterized by XRD, SEM, EDS. The photocatalytic activity of TiO2 was studied by the degradation of methyl orange using the visible light. The results show that the doped is more effective than pure TiO2 ,and reveal that the optimal co-proportion is Cr1. 0%/Ag 0.5% ,the degradation of methyl orange in 3 h can reach 97.63%. |
