The Ag2S/WO3 composites were successfully prepared by two-step method. The composition, morphology and optical properties of the materials were characterized by XRD, EDS and SEM. The results show that the degradation rate of methylene blue (MB) in Ag2S/WO3 composites is about 1.2 times higher than that in WO3 under photocatalytic degradation under the same conditions. The reason is that this study has potential application value in the fields of solar cells and photochemical reactions due to the use of full spectrum to enhance photocatalytic efficiency.
