| 摘 要： | 本课题研究了掺镧纳米二氧化钛的物理特性及光催化活性，探讨了它们之间的关系，通过对甲基橙和罗丹明两种不同结构物质的降解实验，发现掺镧纳米TiO2光催化性能具有广泛性，用于实际印染废水处理，再次验证掺镧能提高TiO2的光催化效能，其中掺镧量为0.02%(质量比，下同）的光催化效果最好。

| Abstract: | In the study,the physical and photocatalytic properties of La-doped TiO2 were investigated . The photocatalytic activity was evaluated by the photocatalytic decomposition of methyl orange and butylrhodamine-B, it was found that the photocatalytic activity of 0.02%La sample was the best , whose photocatalytic activity was proved when it was using to decrease COD of printing and dyeing wastewater. |
