通过对比不同形式玻璃载体负载TiO2紫外光催化降解甲基橙的能力以及不同元素掺杂对光催化降解的影响,探讨了提高TiO2光催化降解有机污水能力的方法。结果表明,毛细玻璃管负载的TiO2由于限域微米空间效应的作用,其光催化能力明显好于玻璃片和玻璃珠载体;同时,比较了TiO2掺杂元素Pb、N和Fe在可见光下的催化能力,得出掺杂Pb为最佳,降解率达到94.8%,以期为负载以及掺杂元素提升TiO2光催化降解污水的处理能力提供借鉴。
The photocatalytic degradation of organic wastewater by TiO2 photocatalytic degradation of organic wastewater by TiO2 photocatalytic degradation of methyl orange was investigated by comparing the photocatalytic degradation of methyl orange with different types of glass supports. The results show that the photocatalytic activity of TiO2 supported by capillary glass tube is obviously better than that of glass plate and glass bead carrier due to the limited spatial effect of micron space. At the same time, the photocatalytic activity of TiO2 doped elements Pb, N and Fe under visible light Ability to obtain the best doping Pb, the degradation rate of 94.8%, with a view to providing reference for the load and doping elements to enhance the TiO2 photocatalytic degradation of sewage treatment capacity.
