  • As a promising environmental remediation technology, the development of efficient and stable photocatalysts with visible light response is one of the important studies in photocatalysis technology. In this work, g-C3N4/porous organic polymers (POPs) composite photocatalysts were prepared via atmospheric solvothermal method. Different ratios of g-C3N4 were in-situ loaded on conjugated porous organic polymers TAPB-DMTP POP synthesized with 1, 3, 5-tris(4-aminophenyl) benzene (TAPB) and 2, 5-dimethoxybenzene-1, 4-diformaldehyde (DMTP) as monomers. The chemical structure and optical properties of g-C3N4/POPs materials were characterized by XRD, FTIR, BET, TGA, UV-Vis DRS, current-time (i-t) and EIS methods. Cr(VI) was selected as the model pollutant, the photocatalytic reduction activities of g-C3N4/POPs photocatalysts with different g-C3N4 loading ratios were explored under visible light conditions, and the effects of pH value, catalyst dosage and substrate concentration were further investigated. The results shows that g-C3N4/POP-2 exhibits the best photocatalytic reduction performance at pH=2 with the reduction efficiency of 99.1% after 30 min of visible illumination. The reduction efficiency of Cr(VI) is significantly improved over g-C3N4/POP-2 compared with pure g-C3N4 and TAPB-DMTP POP, and the fitted first-order kinetics rate are 22.0 times and 2.2 times that of g-C3N4 and TAPB-DMTP POP, respectively. This composite also exhibits excellent photocatalytic stability as the Cr(VI) reduction rate reaches more than 90% after five cycles.
