MIL-101(Fe)/Co₃O₄ composites were synthesized using a facile solvothermal method to establish the superiority of a heterogeneous photochemical catalysis system in the presence of Na₂S₂O₈ with visible light irradiation. In the present system, the MIL-101(Fe)/Co₃O₄ catalyst showed better catalytic performance than the single photocatalytic or chemical catalytic system, implying that the MIL-101(Fe)/Co₃O₄ catalyst can combine both photocatalysis and chemical catalysis well. When tetracycline (TC) is the target pollutant, the highest degradation efficiency can be achieved within 40 min, reaching to 86%. Crystallinity, morphology, and elemental valence of the MIL-101(Fe)/Co₃O₄ composite were explored by using X-ray diffraction (XRD), scanning electron microscopy (SEM) as well as X-ray photoelectron spectroscopy (XPS). From the quenching experiments, it was found that ¹O₂, •SO₄‾, •OH, and O₂‾ make contributions to the effective removal of tetracycline. Apart from that, the recovery and reuse characteristics of MIL-101(Fe)/Co₃O₄ may facilitate the sustainable wastewater treatment.

MIL-101(Fe)/Co ₃ O _{4复合材料在Na 2} S ₂ O ₈存在下和可见光照射下，采用简便的溶剂热法合成了多相光化学催化体系的优越性。在本系统中，MIL-101(Fe)/Co ₃ O ₄催化剂表现出比单一光催化或化学催化体系更好的催化性能，这意味着 MIL-101(Fe)/Co ₃ O ₄催化剂可以很好地结合光催化和化学催化。当四环素（TC）为目标污染物时，40 min内可达到最高降解效率，达到86%。使用 X 射线衍射 (XRD)、扫描电子显微镜 (SEM) 和 X 射线光电子能谱 (XPS) 研究了 MIL-101(Fe)/Co ₃ O ₄复合材料的结晶度、形貌和元素价态. 淬火实验发现¹ O ₂、•SO ₄ ‾、•OH 和O ₂ ‾对四环素的有效去除有贡献。除此之外，MIL-101(Fe)/Co ₃ O _{4的回收再利用特性}可以促进可持续的废水处理。
