| چکیده مقاله |
| Tetracycline (TCN) antibiotic contamination in aquatic environments has emerged as a critical environmental concern due to the persistence, biological activity, and potential ecological risks associated with these pharmaceutical pollutants. Photocatalytic degradation driven by renewable solar energy represents a promising and sustainable approach for the removal of refractory organic contaminants from water. In this study, a TiO2@MIL(Fe)(MT) heterojunction catalyst was prepared via a one pot hydrothermal method using MIL(Fe) and anatase TiO2 as substrates. pathways, thereby suppressing the recombination of photogenerated electron/hole pairs, while the porous MOF promotes tetracycline adsorption and facilitates pollutant catalyst interactions. The formation of the composite heterostructure further enhances light utilization and interfacial charge separation. The optimized catalyst achieved more than 50% tetracycline removal within 120 min under light irradiation. Reactive species trapping experiments demonstrated that hydroxyl radicals (•OH) and photogenerated holes (h+) played dominant roles in the degradation process. Furthermore, the photocatalyst retained substantial photocatalytic activity after five consecutive cycles, demonstrating its potential as a recyclable and efficient material for visible light driven treatment of antibiotic contaminated water. |
