Solar-Driven Photo-Fenton Degradation Of Bisphenol A And Caffeine Using Fe₂O₃/g-C₃N₄ Heterojunctions: A Model Study On Endocrine-Disrupting Pollutants

The widespread occurrence of endocrine-disrupting compounds (EDCs) and caffeine in aquatic environments has raised considerable environmental and public health concerns due to their persistence, bioaccumulation potential, and endocrine-modulating effects. Conventional biological and physicochemical treatment processes often prove inadequate for the effective removal of such micropollutants, particularly at low concentrations. In recent years, solar-driven photo-Fenton processes have garnered significant interest as an efficient and sustainable alternative for the degradation of recalcitrant organic contaminants. Among various photocatalytic systems, Fe₂O₃/g-C₃N₄ heterojunctions have demonstrated enhanced photocatalytic activity due to their favorable band alignment, improved charge carrier separation, and ability to generate reactive oxygen species under solar irradiation. This review explores recent advancements in the application of Fe₂O₃/g-C₃N₄-based photo-Fenton systems for the treatment of EDCs and caffeine in aqueous matrices.
