In this study, a novel photocatalyst for efficiently eliminating toxic and harmful antibiotics from water bodies was prepared successfully. Precisely, MoS₂/ZnWO₄ (MSZW) heterostructures were prepared using a facile hydrothermal technique. The constructed samples were characterized by using structural, morphological, diffuse reflectance spectroscopy, and photoluminescence measurements. The efficiencies of the catalysts were investigated using the removal of tetracycline (TC) antibiotic under stimulated solar light irradiation. Among the prepared photocatalysts, the optimal MSZW-10 heterostructure displayed superior photocatalytic performance and degrade ~97.40% of TC within 105 min. Moreover, the photocatalytic performance of MSZW-10 is approximately ~6.18 and ~10.77 times greater over pure MoS₂ and ZnWO₄, respectively. The progress in the photocatalytic performance chiefly owing to its improved partition of charge carriers, the robust positive synergistic effect of suitable positions of energy levels, improved light absorption ability, and enhanced interfacial charge transfer between MoS₂ and ZnWO₄. The MoS₂/ZnWO₄ composite exhibits significantly enhanced photocatalytic performance as well as excellent reusability performance, thus indicating its applicability in wastewater treatment.

本研究成功制备了一种新型光催化剂，可有效去除水体中的有毒有害抗生素。准确地说，MoS ₂ /ZnWO ₄(MSZW) 异质结构是使用简便的水热技术制备的。通过使用结构、形态、漫反射光谱和光致发光测量来表征构建的样品。通过在受激太阳光照射下去除四环素 (TC) 抗生素来研究催化剂的效率。在制备的光催化剂中，最佳的 MSZW-10 异质结构显示出优异的光催化性能，并在 105 分钟内降解约 97.40% 的 TC。此外，MSZW-10 的光催化性能是纯 MoS ₂和 ZnWO _{4 的}约 6.18 倍和 10.77 倍， 分别。光催化性能的进步主要归功于其改进的电荷载流子分配、合适能级位置的强大正协同效应、改进的光吸收能力以及增强的 MoS ₂和 ZnWO ₄之间的界面电荷转移。MoS ₂ /ZnWO ₄复合材料表现出显着增强的光催化性能以及优异的重复使用性能，从而表明其在废水处理中的适用性。
