. Through a series of redox reactions, it achieved a 95.4% degradation efficiency for TCH within 120 min. Furthermore, it disrupted the cell membrane integrity of Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) within 30 min, leading to cell death and achieving high antibacterial rates of 99.38% and 98.77%, respectively. The electron transfer mechanism during the photocatalytic reaction was revealed through density functional theory (DFT) calculations. This work provides a novel strategy for developing a photocatalytic platform capable of degrading environmental antibiotic pollutants while simultaneously inactivating S. aureus and E. coli, demonstrating broad application prospects in environmental remediation.
