摘　　要：多孔材料与纳米TiO2复合是目前光催化领域的研究热点。多孔材料作为吸附中心可为TiO2光催化剂提供高浓度反应环境,提高催化剂矿化效率并抑制催化剂失活、解决催化剂分离等难题;目前,国内外研究者对TiO2/AC(活性炭)的光催化机理、TiO2与AC的协同作用机理、TiO2/AC的制备方法进行了较为深入的研究。对TiO2/AC复合材料的制备方法进行了综述,比较了各种制备方法的优缺点。For photo-catalysis field,the combination of porous adsorbent with nano-sized TiO2 photo-catalyst has been the focus of the research.Porous adsorbent can provide high organic concentration environment for loading TiO2 photo-catalyst to enhance the photo-catalytic rate and efficiency,retarding catalyst deactivation and resolving the separation problem of nano-sized TiO2.The photo catalytic mechanism of TiO2/AC,synergistic effect between TiO2 and AC,preparation methods of TiO2/AC in China and aboard were studied.The preparation methods of TiO2 photocatalyst-activated carbon（AC） composite TiO2/AC were reviewed,and the advantages and disadvantages of the methods were compared.
