    Abstract:
    In recent years, antibiotic pollution has received increasing attention. Tetracycline (TC) is a commonly used antibiotic in human medicine. The presence of TC in the environment inhibits bacterial growth and enhances antibiotic resistance in organisms. In this study, MoS2/MIL101(Fe) nanocomposites are mainly constructed to remove TC pollutants using photo-fenton technology and improve the ability of photo-fenton to treat antibiotic pollutants. The system shows excellent performance for the removal of tetracycline, and the removal rate of TC by MoS2/MIL101(Fe) nanocomposite reaches 93%. Through a series of experiments such as XRD, FTIR, XPS, SEM, ESR, UV-VIS DRS, Band gap energies, photocurrent response (I-t) and Zeta potential-pH, the results show that the system promotes the Fe3+/Fe2+ cycle reaction, significantly promotes the photodecomposition of H2O2 and the formation of O2- and •OH, and broadens the pH range of the photo-fenton oxidation reaction. The combination of the metal-assisted catalyst MoS2 and the metal-organic framework MIL101(Fe) has been demonstrated to effectively enhance the ability of the Fenton reaction for the treatment of antibiotics, showcasing innovative synergy. Furthermore, the utilization of molybdenite as a substitute for MoS2 in the preparation process avoids environmental pollution associated with the synthesis of MoS2. In this study, a novel, efficient, energy-saving and environmentally friendly catalyst for the removal of tetracycline has been developed, and has a wide range of applicability.
