Recent advances in cadmium sulfide (CdS)-based photocatalysts

Organic compounds from different industries produce a range of problematic pollutants in wastewater. Cadmium sulfide (CdS) based photocatalyst as a typical photocatalytic material, due to its high efficiency and stability, shows great potential in the field of environmental restoration, which has strong visible light absorption, suitable band energy level and excellent electron charge transport performance. Research on degradation of organic pollutants using cadmium sulfide (CdS) based photocatalyst has made significant progress. In order to improve the rate and ability of cadmium sulfide (CdS) based photocatalyst to degrade pollutants, this paper introduces various strategies to modify the shape and structure of photocatalyst to improve its performance. In addition, the reaction conditions were optimized, and the mechanism of photocatalytic degradation was discussed. In conclusion, the research of cadmium sulfide based photocatalysts provides valuable insights for the degradation of organic pollutants and offers hope for future application in ecological environmental protection.
