Although metal organic frameworks (MOFs) presented excellent photocatalytic activities, the rapid recombination of light-induced charges and low visible light utilization efficiency hindered their practical applications. In this work, a novel heterojunction photocatalytic materials of MOFs-based semiconductor, the flower-like hybrids (UiO-66@MoS₂) (UMS), were fabricated via a facile electrostatic induction self-assembly method. A series of characterizations, such as SEM, TEM, EDS, EDX, XRD, XPS, BET, FT-IR and TGA, indicated the successful synthesis of hybrid materials and revealed that MoS₂ nanosheets grew on the surfaces of the UiO-66 with an intimate interaction, and then formed a flower-like structure through self-assembly, which effectively prevented recombination of photogenerated charge carriers. Comparing with pure UiO-66 and MoS₂, the flower-like hybrids (UMS) exhibited remarkable performance for the degradation of lomefloxacin hydrochloride (LOM) under visible-light irradiation. Furthermore, its photoelectrochemical properties were characterized by photoluminescence spectra (PL), UV–vis diffuse reflectance spectra (DRS), and electrochemical impedance spectra (EIS). Moreover, the possible photocatalytic mechanism of UiO-66@MoS₂ was investigated. It indicated that its photocatalytic activity was enhanced by the synergetic effect of MoS₂ and UiO-66. In summary, a novel heterojunction photocatalysts, being fabricated via a facile method, could be applied to effectively photocatalytic treatment of medical wastewater.

尽管金属有机骨架（MOF）表现出出色的光催化活性，但光诱导电荷的快速重组和低可见光利用效率阻碍了它们的实际应用。在这项工作中，通过简便的静电感应自组装方法，制备了基于MOFs的半导体的新型异质结光催化材料，即花状杂化体（UiO-66 @ MoS ₂）（UMS）。SEM，TEM，EDS，EDX，XRD，XPS，BET，FT-IR和TGA等一系列表征表明成功合成了杂化材料并揭示了MoS ₂纳米片以紧密的相互作用生长在UiO-66的表面上，然后通过自组装形成花状结构，从而有效地防止了光生电荷载体的重组。与纯UiO-66和MoS _2相比，花状杂种（UMS）在可见光照射下具有出色的降解盐酸洛美沙星（LOM）的性能。此外，它的光电化学特性由光致发光光谱（PL），紫外可见漫反射光谱（DRS）和电化学阻抗光谱（EIS）表征。此外，研究了UiO-66 @ MoS ₂可能的光催化机理。表明MoS ₂的协同作用增强了其光催化活性。和UiO-66。总之，通过一种简便的方法制备的新型异质结光催化剂可用于有效地光催化处理医疗废水。
