The widespread use of antibiotics has led to significant water pollution. Photocatalysis can effectively degrade antibiotics, but the performance is greatly limited by photogenerated carrier recombination in photocatalytic material g-C3N5. Constructing heterojunctions enhance interfacial charge transfer, leading more stable and efficient photocatalysis. This study synthesized a Fe2O3/g-C3N5 heterojunction using solvothermal method. Z-scheme transfer mechanism facilitated separation carriers, preserving photoelectrons holes with high redox activity. process generated substantial amount highly reactive free radicals such as ·O2- ·OH, enabling degradation tetracycline (TC). Under optimal conditions initial concentration TC was 200 mg/L, quality ratio Fe2O3 g-C3N5 1:2, catalyst dosage 50 mg pH = 7.0, rate reached 92.46% within 60 min visible light irradiation. activity's enhancement attributed broad spectral absorption effective separation. Furthermore, be affected presence inorganic salt ions HCO3- CO32-.
