摘要:
Photo-Fenton advanced oxidation process has received intense attention since it can exert the synergistic effect of photocatalysis and Fenton reaction. Herein, 2D/2D α-Fe2O3/g-C3N4 S-scheme heterojunctions were successfully fabricated and applied in photo-Fenton degrading tetracycline hydrochloride (TC). The crystalline phases, morphologies, microstructures, textural structures and optical properties of as-prepared heterojunctions were thoroughly characterized. By comparison and optimizing, the 5.26 wt% 2D/2D α-Fe2O3/g-C3N4 heterojunction exh...
