摘　　要：在油胺中合成Cu1.94S/ZnS,并将其分散到乙醇溶液中在磁力搅拌下与金纳米粒子复合,制备了Au/Cu1.94S/ZnS三元纳米复合物,利用X射线衍射仪(XRD)、透射电子显微镜(TEM)、紫外可见分光光度计(UV-Vis)等分析测试手段对所得产物进行表征,考察了在可见光下Au/Cu1.94S/ZnS纳米复合物对染料RhB的光催化降解性质.结果显示:Au/Cu1.94S/ZnS纳米复合物具有优异的光降解性能.The Au/Cu194 S/ZnS nanocomP0sites 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/Cu1.94S/ZnS nanocomposites revealed much higher photocatalytic activity.
