Ag2SO3 based composites, ASO/Ag2S (ASO=Ag2SO3/Ag2SO4) and ASO/AgX (X=Cl, Br), were prepared by a simple and mild gas–liquid reaction and ion-exchange method. Scanning electron microscope (SEM), energy-dispersive X-ray spectroscopy (EDX), X-ray powder diffraction (XRD) and UV–vis diffuse reflectance absorption spectra (DRAS) were performed to characterize the as-synthesized materials. The photocatalytic performances of Ag2SO3, ASO, ASO/Ag2S and ASO/AgX (X=Cl, Br) were evaluated by the photodegradation of rhodamine B (RhB) under simulated visible light. The formation of photo-reduced Ag nanoparticles (NPs) during visible light illumination resulted in plasmon-induced photodegradation of RhB.
