MIL-101(Fe)/WS catalyst was composited using a solvothermal method. To study the physical and chemical properties of the composite material, a series of characterizations such as scanning electron microscope (SEM), X-ray diffraction (XRD), and catalytic experiments were carried out. The photocatalysis of the prepared catalyst in the degradation of tetracycline was investigated using persulfate (PS, NaSO) as a cocatalyst under visible light illumination. The above system can remove about 80% of tetracycline within 40 min. After three cyclic experiments, the material showed good recycling. According to material characterization and various experimental results, the enhanced performance of the material was attributed to the reduction of the recombination efficiency of photogenerated e and h, and activated persulfate to produce a large number of free radicals such as O, SO and O produced by the active sites provided by the catalyst's high specific surface area.
MIL-101(Fe)/WS 催化剂采用溶剂热法合成。为了研究复合材料的物理化学性质，进行了一系列的表征，如扫描电子显微镜（SEM）、X 射线衍射（XRD）和催化实验。在可见光照射下，以过硫酸盐（PS，NaSO）为共催化剂，研究了制备的催化剂在四环素降解中的光催化性能。在上述体系中，四环素在 40 分钟内可去除约 80%。经过三次循环实验，该材料表现出良好的循环性能。根据材料表征和各种实验结果，材料性能的增强归因于光生电子和空穴的复合效率的降低，以及由催化剂高比表面积提供的活性位激活过硫酸盐产生大量的自由基，如 O、SO 和 O。
