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.
