| Abstract: | The Au/Cu1.94S/ZnS nanocomposites were synthesized in oleylamine (OLA) by a facile method ,then composited with Au nanoparticles in the ethanol solution .The structure and morphology of the as‐synthesized samples were characterized by X‐ray diffraction (XRD ) , transmission electron microscopy ( TEM ) , ultraviolet‐visible‐near‐infrared spectrophotometer (UV‐Vis) .The photocatalytic activity of the as‐synthesized samples was evaluated by monitoring the degradation of Rhodamine B (RhB ) solution . The results showed that Au/Cu1.94 S/ZnS nanocomposites revealed much higher photocatalytic activity . |
