摘要
采用水热法制备了ZnS量子点纳米材料,利用X射线衍射仪(XRD)和透射电子显微镜(TEM)对所制备的样品进行了结构和形貌表征.同时以环境中存在的抗生素污染物环丙沙星(CIP)为降解对象,研究了ZnS量子点的光催化性能.经研究表明,成功制备了ZnS量子点材料,且ZnS量子点材料在紫外光照射下能够明显的降解环境中存在的抗生素环丙沙星(CIP)污染物,降解效率达到80%,表现出良好的光催化性能,但其在可见光下照射下的光催化性能明显降低,降解效率仅有45.75%.
In this paper,ZnO quantum dot nanomaterials were prepared by hydrothermal method and the structure and morphology of the prepared samples were characterized by XRD and transmission electron microscopy（ TEM）. At the meantime,it is studied photocatalytic properties of ZnS quantum dots using antibiotic contaminants ciprofloxacin（ CIP） in the environment as the object of degradation. The study showed that ZnS quantum dot successfully prepared revealed good photocatalytic properties under UV irradiation,it can effectively degraded the antibiotic contaminants ciprofloxacin（ CIP） in the environment,but its catalytic activity under visible light was not high and its removal efficiency was only 45. 75%.
