Abstract
AbstractPoly(phenyl‐1,3,5‐yl)‐benzene/g‐C3N4 (PPB/g‐C3N4) catalysts were prepared by in situ for the removal of Rhodamine B from polluted water under visible light irradiation. In addition, the catalytic behavior of PPB/g‐C3N4 composites has been studied by using XRD, TEM, UV‐vis DRS and PL. The results show that PPB has been successfully loaded on g‐C3N4, PPB/g‐C3N4‐0.4 composite have good photo‐Fenton‐like catalytic performance. In the case of PPB/g‐C3N4+H2O2 composite, the RhB photo‐ removal efficiency was ∼96 % in 50 min. The removal rate of PPB/g‐C3N4+H2O2 composite is 9.4 times higher than that of pure g‐C3N4. Owing to the higher surface area and polymer heterojunction (PHJ), PPB/g‐C3N4‐0.4 composite have the superior photo‐Fenton‐like catalytic activity. Moreover, PPB/g‐C3N4 composite rendered excellent stability. Therefore, S‐scheme polymer heterojunction PPB/g‐C3N4 composite was synthesised without metal in situ, which are potential photo‐Fenton‐like catalyst for wastewater treatment under visible‐light irradiation, in which provided a new integration strategy.
