Herein, we report the enhanced photoreduction degradation of polybromodiphenyl ethers with Fe₃O₄-g-C₃N₄ under visible light irradiation (>420 nm). A series of high activity photocatalysts Fe₃O₄-g-C₃N₄ (named FeOCN-<i>x</i>) have been synthesized by an <i>in situ</i> growth method. The characterization of the prepared FeOCN-<i>x</i> nanocomposites has been examined by SEM, TEM, ultraviolet-visible diffuse reflectance spectroscopy, a vibrating sample magnetometer, X-ray diffraction, X-ray photoelectron spectroscopy and Brunauer-Emmer-TRSC advancesEnhanced photoreduction degradation of polybromodiphenyl ethers with Fe₃O₄-g-C₃N₄ under visible light irradiation.PMC9078955No. 21107073 and 21477080Chen XQWang QYe WDChen CCShao YYLiu CLSun CYGu JYfalseEnhanced photoreduction degradation of polybromodiphenyl ethers with Fe₃O₄-g-C₃N₄ under visible light irradiation.As typical persistent organic pollutants, polybrominated diphenyl ethers (PBDEs) have aroused high environmental concern due to their toxicity and recalcitrant degradation.
