CdS is widely used in photocatalytic research due to its unique photoelectrochemical properties. CdS recombination with narrow bandgap semiconductors and organic compounds plays an important role in photocatalyst exploration. In this study, a cucurbit[6]uril (Q[6]) composite and Ag 2 S-doped cadmium sulfide photocatalyst (Q[6]/CdS-Ag 2 S) were prepared by chemical precipitation method and their composite was characterized by different methods. The experiment is designed to use visible light as the light source and Rhodamine B as the simulated pollutant. Meanwhile, the effects of Q[6] on the photocatalytic performance of CdSAg 2 S were investigated. The results showed that the morphology of Q[6]/CdS-Ag 2 S composite after cucurbit[6]uril recombination was similar to cauliflower, while the particle size become smaller. Catalytic performance of the composite catalyst Q[6]/CdS-Ag 2 S was significantly higher than that of CdS-Ag 2 S, the photocatalytic reaction lasts 110 min, showing the catalytic degradation effciency of 92.4% using 15 mg composite catalyst on 100 mL, 6 mg/L Rhodamine B solution.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
