ZnO/CuS heterojunction photocatalysts are prepared via the successive ionic layer adsorption reaction method,and the supported ZnO/CuS@CN catalysts are successfully prepared through coupling ZnO/CuS with cellulose network(CN).The elemental composition,micro-morphology and electrical properties of the catalysts are characterized by means of X-ray diffraction(XRD),X-ray photoelectron spectroscopy(XPS),scanning electron microscopy(SEM),infrared spectroscopy(FT-IR)and electrochemical impedance spectroscopy(EIS).The performance of the catalysts for the degradation of organic pollutants is evaluated by taking rhodamine B as the target.Results show that the degradation rate of 50 mg·L-1 rhodamine B by ZnO/CuS@CN reaches 84.1％after having been irradiated by simulated solar for 60 minutes.Free radical trapping experiments show that·O2 is the main active matter.ZnO/CuS@CN shows good degradation effects on a variety of organic pollutants.
