  • 摘要: 使用简单丙三醇-水混合溶剂热法制备碱式碳酸锌微纳米球前驱物，经退火得到ZnO微纳米球，通过液相沉淀法把AgBr纳米颗粒固定在ZnO微纳米球表面，在AgBr 和ZnO之间形成异质结有效地增强了 AgBr/ZnO复合物的光催化活性。利用X射线衍射仪(XRD)、扫描电子显微镜(SEM)、能谱仪(EDS)与紫外可见分光光度计对样品物相、形貌、元素组成及光学性质进行表征。在可见光条件下，研究ZnO及不同AgBr量的ZnO/AgBr复合材料的光催化活性，结果表明：循环修饰5次AgBr的ZnO微纳米球(AgBr颗粒负载质量分数为5%，5%-AZ)样品对罗丹明B的光催化降解性能最好；该复合材料的光催化可重复性使用结果显示循环使用次数的增加，其光催化性能有下降的趋势。通过分析可知在光照条件下 AgBr的分解引起异质结构变化。
    Abstract: ZnO micro/nanospheres were obtained by calcination treatment of a pre-synthesized basic zinc carbonate precursor micro/nanospheres prepared using a simple, glycerol-mediated solvothermal method. AgBr nanoparticles were then immobilized on the surface of the ZnO micro nanospheres by liquid phase precipitation method. A hetero-junction structure was formed between AgBr and ZnO, which efficiently enhanced photocatalytic activity of AgBr/ZnO composite. The phase, morphology, elemental composition and optical spectra of the samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and UV-vis spectrophotometer, respectively. The photocatalytic activities of ZnO and ZnO/AgBr composites with different AgBr contents were investigated under visible light illumination. The experimental results show that the ZnO micro/nanospheres modified with AgBr about 5 cycle times (the loading mass percent of AgBr particles is 5%, 5%-AZ) have the best photocatalytic activity for the degradation of rhodamine B(RhB). Renewable photocatalytic activity of the sample shows a downward trend with the cycle times increased. The reason can be attributed to the change of heterogeneous structure caused by the decomposition of AgBr under illumination.
