Nanometer CdS preparation and its photocatalytic performance under visible light irradiation

In this paper, CdS nanometer particles are successfully synthesized by hydrothermal method and its photo catalytic performance was evaluated via degradation Ciprofloxacin under visible light irradiation. The morphology, size and structure are characterized by scanning electron microscopy, X-ray diffraction spectroscopy, UV-vis absorption spectrophotometer, respectively. The results show that CdS exhibit excellent photo catalytic performance for degradation Ciprofloxacin with a maximum removal rate of over 95% at 60 min under visible light irradiation due to its higher visible light absorption and comparatively low electron-hole pair recombination. The possible mechanism of the photo catalytic degradation processes is proposed.
