| Abstract (English): | Photocatalytic technology has significant advantages in degrading pollutants in the fields of environmental remediation and catalysis. In response to the disadvantages of large band gap and high electron-hole pair recombination efficiency of traditional metal oxides, the conductive polymers modification is put forward as an efficient method to enhance the photocatalytic activity of metal oxide. On the basis of the classification, preparation methods and characterization methods of photocatalysts, the mechanism and application of conductive polymer/metal oxide photo⁃catalysts were reviewed. The photocatalytic activity enhanced mechanism of conductive polymer/metal oxide included the photosensitization effect of conductive polymer, the synergetic effect between conductive polymer and metal oxide. In the end, the challenges of conductive polymer/metal oxide photocatalysts were proposed, including the control of energy band of metal oxide, the relationship between gap-structure of energy band and photosensitization-synergetic effect, effect of functional groups on photocatalytic activity of conductive polymer/ metal oxide photocatalysts. Outlooks on oxidizing mechanism, structure-activity relationship, theoretical simulation and novel characterization of photocatalytic process were prospected, and the results could provide the theoretical support for design and applications of high efficient photocatalysts.
