摘要
ATP/g-C3N4 (graphitic carbon nitride) consisting of g-C3N4 film in-situ growth on the surface of attapulgite (ATP) rod was prepared via a hydrothermal process. Then ATP/g-C3N4 was used as a carrier to uniformly load LaCoO3 nano-particles to prepare Z-scheme ATP/g-C3N4/LaCoO3 heterojunction photocatalysts. The samples obtained were characterized by X-ray diffraction, transmission electron microscopy, ultraviolet-visible, photoluminescence, Brunauer-Emmett-Teller, specific surface area analysis and photo electrochemical analysis. The oxidative removal ability of ATP/g-C3N4/LaCoO3 at different loadings of LaCoO3 to benzothiophene (DBT) in model gasoline was investigated under visible light. The results show that ATP/g-C3N4/LaCoO3 composites dramatically enhance the visible light response, the absorption capacity and the separation of photogenerated electron-hole pairs, compared to ATP/g-C3N4 andLaCoO3. After 150-min irradiation, the desulfurizing rate of 50%-ATP/g-C3N4/LaCoO3 can achieve 85.3%. © 2020, Editorial Department of Journal of the Chinese Ceramic Society. All right reserved.
