摘　　要：以BaTiO3作为光催化剂,将其负载到石墨烯片(GR)上形成复合结构,通过气相沉积将聚吡咯(PPy)负载到GR/BaTiO3结构上形成PPy包覆的PPy/GR/BaTiO3光催化剂。分析PPy/GR/BaTiO3光催化剂的形貌,并对其光催化性能进行表征。研究结果表明:由于GR和PPy之间的强共轭效应,可以极大地增加材料的比表面积。同时,GR作为电子接收体,可改善材料中光生载流子的快速复合,因此,相比于PPy和GR材料的光催化降解性能,PPy/GR/BaTiO3光催化剂降解性能得到明显提高。Using BaTiO3 as a photocatalyst, load it on a graphene sheet(GR) to form a composite structure, and load polypyrrole(PPy) on the GR/BaTiO3 structure by vapor deposition to form a PPy-coated PPy/GR/BaTiO3 photocatalyst. Analyze the morphology of PPy/GR/BaTiO3 photocatalyst and characterize its photocatalytic performance. The research results show that: due to the strong conjugate effect between GR and PPy, the specific surface area of the material can be greatly increased. At the same time, as an electron acceptor, GR can improve the rapid recombination of photo-generated carriers in the material. Therefore, compared with the photocatalytic degradation performance of PPy and GR materials, the degradation performance of PPy/GR/BaTiO3 photocatalyst has been significantly improved.
