Abstract
Abstract Ag2WO4/CdS composites with different concentrations of CdS nanoparticles were synthesized. The morphology of the as-synthesized particles was studied by SEM and TEM, and the surface chemical states and elemental composition were investigated by XPS. The photocatalytic properties of both Ag2WO4 and Ag2WO4/CdS were investigated by decomposing RhB under visible light. The conclusion indicated that the addition of CdS into Ag2WO4 could improve the photocatalytic performance, while an excessive amount of CdS could decrease the photocatalytic activity. The mechanism for the increased photocatalytic performance was investigated by UV–Vis absorption spectrum, EIS Nyquist plots, and transient photocurrent responses. The increased photocatalytic performance could be attributed to the increased electron/hole separation and charge carrier transfer, due to the presence of CdS on Ag2WO4.
