The invention relates to the technical field of organic-inorganic hybrid materials, and discloses an organic-inorganic composite photocatalytic film and a preparation method and application thereof. The preparation method comprises: contacting the mixed solution I containing poly-3-hexylthiophene with modified conductive carbon black and tungsten trioxide in turn, then uniformly coating the obtained coating solution and then curing to form a film to obtain a composite film, and then applying the composite film The film is sequentially contacted with a silver nitrate solution and a disodium hydrogen phosphate solution, and an organic-inorganic composite photocatalytic film immobilized with silver/silver phosphate is obtained by a photoreduction method. Through the synergistic effect among poly-3-hexylthiophene, tungsten trioxide, silver/silver phosphate and conductive carbon black modified by a silane coupling agent, the invention can significantly improve the utilization rate of visible light and the photocatalytic degradation efficiency, thereby realizing the Efficient adsorption of pollutants in water bodies. |
