论述了二氧化钛（TiO2）在活性碳纤维（ACF）上的负载方式，总结了TiO2/ACF复合光催化剂的表面形态特征和结构特点，介绍了TiO2/ACF复合光催化剂光催化氧化水中有机物吸附、富集、光催化、原位再生的过程。活性碳纤维可富集目标物、捕获中间产物，还可抑制中间有害产物的生成及热处理过程中TiO2的相变。讨论了目标物、负载方法、负载量等因素对有机物氧化速率的影响。TiO2、ACF的复合将对光催化剂的应用技术产生积极影响，指出了研究中应该解决的问题。

The preparation methods of TiO2/ACF composite photocatalysts are reviewed. The surface morphology, structural characteristics of TiO2/ACF composite photocatalysts and the effect of concentration, adsorption, photocatalysis and recovery of TiO2/ACF catalyst are analyzed. It is shown that the carbon fiber in the composite affects the concentration of the targeted pollutant and the capture of intermediate products, and may reduce the harmful products of the middle generation．In addition, it has the advantage of suppressing the phase transformation from anatase to mille. The mechanism of the synthetical effect of activated carbon fibers and titanium dioxide is studied based on the morphology and structure of the composite photocatalyst, and the targets, the preparation methods, the loading of TiO2 and other factors which influence the oxidation rate are discussed. A beneficial effect is shown in a practical application of photocatalysis technology to TiO2/ACF composite photocatalysts. The problems that should be solved in future studies are pinpointed.
