Abstract: Advanced oxidation processes (AOPs) using hydroxyl radicals (▪OH) as oxidizing agents are a promising technology. Herein, a feasible strategy is developed to initially construct carbazole-based D-π-A type conjugated polymer (PBNCZ) via the oxidative coupling. Additionally, introducing -COO- through Cyano hydrolysis extends its conjugated structure and improves the energy band structure, which greatly facilitates the generation of ▪OH as well as the enrichment of pollutants. Detailed experiments and theoretical calculations have proved that the introduction of -COO- enhances the adsorption of O2 and bisphenol A (BPA), optimizing the reaction path of ▪OH. Thus, it completely decomposes 10 ppm of BPA within just 10 min, exceeding all previously organic photocatalysts. Meanwhile, the efficiency of photocatalytic H2O2 production by PBNCZ-COO- reaches 1719.03 μmol h-1g-1 under visible light. This multifunctional material with high adsorption capacity, photodegradation efficiency, and photocatalytic H2O2 production activity provides a solid foundation for the preparation of organic photocatalysts.
