| 摘 要： | 采用简单的两步水热法制备出了锆基金属有机骨架和钼酸铋的复合材料MOF-808/Bi2MoO6。通过X射线粉末衍射、傅里叶红外光谱、扫描电子显微镜、透射电子显微镜、X射线光电子能谱、紫外可见漫反射光谱、N2吸附-脱附测试和电化学测试对所制备材料的组成、微观结构、光学性质以及光生载流子的复合效率进行了分析。与纯Bi2MoO6和MOF-808相比，0.5%-MOF-808/Bi2MoO6复合材料展示出了较高的光催化活性，在可见光照射120 min时对抗生素环丙沙星(CIP)的降解率达89.7%。通过自由基捕获实验，证明了·O2-是主要活性物种，基于此我们提出了可能的光催化降解机理。

| Abstract: | Zirconium-based metal-organic framework and bismuth molybdate composite (MOF-808/Bi2MoO6) was prepared by a simple two-step hydrothermal method. The phase composition, microstructure, optical properties, and photogenerated charge recombination efficiency of the materials were analyzed by X-ray powder diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, UV visible diffuse reflectance spectroscopy, N2 adsorption-desorption testing, and electrochemical testing. Compared with pure Bi2MoO6 and MOF-808, the 0.5%-MOF-808/Bi2MoO6 composite exhibited higher photocatalytic activity, and the degradation rate of the antibiotic ciprofloxacin (CIP) reached 89.7% under visible light irradiation for 120 min. Through radical trapping experiments, it was proved that·O2- was the main active species, based on which we proposed a possible photocatalytic degradation mechanism. |
