摘　　要：以对苯二甲酸和4,4'-双(咪唑基)-二苯基醚为配体,采用溶剂热法合成了锌基金属有机框架材料(Zn-MOF),再经高温煅烧制备了ZnO^(*)(*代表氧空位)。使用X射线粉末衍射(XRD)对产物的物相进行了表征,使用紫外-可见漫反射光谱仪对Zn-MOF和ZnO^(*)的带隙宽度进行了分析。分别以紫外光和可见光为光源,四环素(TC)为目标污染物,通过光催化降解实验,对Zn-MOF和ZnO^(*)光催化降解四环素的性能进行了探究。实验结果表明,在太阳光驱动下,相较Zn-MOF,ZnO^(*)对四环素的催化降解性能得到了大幅提升。Zn-based metal-organic framework material(Zn-MOF)was synthesized by solvothermal method applied terephthalic acid and 4,4'-bis(imidazol-yl)-diphenyl ether as ligands.Then,ZnO^(*)was prepared by high-temperature calcination.The phase was characterized by X-ray powder diffraction(XRD)analysis.The bandgap widths of Zn-MOF and ZnO^(*)were analyzed by UV-vis diffuse reflectance spectroscopy.UV light and visible light were selected as the light source,tetracycline(TC)was selected as the target pollutant,the photocatalytic degradation performance of tetracycline of Zn-MOF and ZnO^(*)were investigated by photocatalytic degradation experiments.The experimental results showed that under the drive of sunlight,compared with Zn-MOF,the catalytic degradation of ZnO^(*)on tetracycline was significantly improved.
