摘要
研究了掺镧纳米TiO2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,掺镧摩尔分数为0 02%时光催化效果最好。
Physical and photocatalytic properties of lanthanum-doped nanocrystalline titania were investigated, as well as their relationship. Photocatalytic activity was tested via photocatalytic decomposition of methyl orange and butylrhodamine-B. The results showed that doping of lanthanum enhanced the photocatalytic activity of titania, and titania doped with 0.02% mole fraction of lanthanum exhibited the best activity. The catalyst is applicable to treatment of printing and dyeing wastewater.
