TiO2光催化在废水处理、空气净化等环保领域展示出诱人前景。纳米TiO2光催化剂的负载化是实现其产业化的关键步骤之一。多孔吸附剂与纳米TiO2复合可提供对污染物的高浓度吸附环境,提高TiO2分散度,解决催化剂分离难题,是光催化领域的研究热点之一。本文对近年来国内外多孔吸附剂与纳米TiO2复合的发展情况进行了综述,着重介绍了负载型TiO2光催化剂的固定化方法、多孔吸附剂类型以及负载对光催化活性的影响机理。
TiO2 photocatalysis in the wastewater treatment, air purification and other environmental protection to show attractive prospects. The loading of nano-TiO2 photocatalyst is one of the key steps to realize its industrialization. Porous adsorbents and nano-TiO2 composite can provide a high concentration of pollutants adsorption environment, improve the TiO2 dispersion, to solve the problem of catalyst separation, is one of the hot spots in the field of photocatalytic. This review summarizes the development of the composite of porous adsorbent and nano-TiO2 at home and abroad in recent years, and emphatically introduces the immobilization method of supported TiO2 photocatalyst, the type of porous adsorbent and the influence mechanism of photocatalytic activity.
