英文摘要：

Activated carbon （AC） or activated carbon fiber （ACF） can be used as good catalyst support for its high specific surface area and strong adsorption capability. AC and ACF have been paid much attention by many researchers because they can enhance the photocatalytic degradation efficiency of TiO2 for organic contamination. The structure and characteristics of TiO2 photocatalyst and its doping modification method are introduced at first. And then a variety of preparation techniques for TiO2/AC （or TiO2/ACF） supported photocatalytic materials are summarized in detail. Based on this, several important influence factors on the photocatalytic degradation of various contaminations are discussed. The problem of supported TiO2 photocatalyst to be solved and its development direction are pointed out.
