In this paper, ZnS quantum dot nanomaterials were prepared by means of hydrothermal method and the structure and morphology of the prepared samples were characterized by XRD and transmission electron microscopy (TEM). At the same time, the photocatalytic properties of ZnS quantum dots were studied using antibiotic contaminants ciprofloxacin (CIP) in the environment as the object of degradation. The study showed that the successfully prepared ZnS quantum dot has good photocatalytic property under UV irradiation, it can effectively degrade the antibiotic contaminant ciprofloxacin in the environment, but its catalytic performance under visible light is not high and its degradation efficiency is only 45.75%.
