摘　　要：By dip-coating poly（3,4-ethylenedioxythiophene）/poly（styrenesulfonate）,an organic semiconductor,on slide glass and then calcining at a low temperature of 100 ℃,the organic-inorganic composite TiO2-PEDT/PSS film was prepared.In the TiO2-PEDT/PSS dual-layer structure,photo-generated electrons in the TiO2 layer inject into the PEDT/PSS layer under UV illumination,and the recombination of photo-generated electrons and holes in the TiO2 layer is suppressed consequently,so the photocatalytic activity of this composite film is increased significantly compared with TiO2 film.By dip-coating poly （3,4-ethylenedioxythiophene）/poly （styrenesulfonate）, an organic semiconductor, on slide glass and then calcining at a low temperature of 100 ℃, the organic-inorganic composite TiO2-PEDT/ PSS film was prepared.
