摘要
印染废水产量大且难处理,TiO_(2)光催化处理方法可高效降解印染废水,但TiO_(2)存在禁带宽度大、载流子易复合、易团聚等缺陷,限制了其应用.近年来采用离子掺杂、表面贵金属沉积、表面光敏化、半导体复合、负载化等多种方法对TiO_(2)进行改性以提高其性能.本文对目前这些TiO_(2)改性材料处理印染废水的研究进行了总结,并指出今后的发展趋势.
The dyeing wastewater is large in quantity and difficult to be treated,but TiO_(2) photocatalysis can efficiently degrade the dyes in wastewater.However,the application of TiO_(2) is limited due to its big band gap,easy carrier recombination,and agglomeration.In recent years,TiO_(2) has been modified by ion doping,noble metal deposition,photosensitization,semiconductor recombination,and loading to improve its properties.This paper summarized the research on the treatment of dyeing wastewater with different modified materials,and pointed out the development trend in the future.
