AB  - High-efficiency photocatalysts are of great significance for the application of 
      photocatalytic technology in water treatment. In this study, N/Cu co-doped ZnS 
      nanosphere photocatalyst (N/Cu-ZnS) is synthesized by a hydrothermal method for 
      the first time. After doping, the texture of nanosphere becomes loose, the 
      nanometer diameter is reduced, making the specific surface area of catalyst 
      increased from 34.73 to 101.59 m(2)/g. The characterization results show that 
      more ZnS (111) crystal planes are exposed by N/Cu co-doping; the calculations of 
      density functional theory show that N/Cu co-doping can increase the catalytic 
      activity of the ZnS (111) crystal plane, enhance the adsorption capacity of (111) 
      crystal plane to O(2), and promote the generation of *O(2)(-). The energy levels 
      of the introduced impurities can be hybridized with the energy levels of S and Zn 
      at the top of valence band and the bottom of conduction band, which makes the 
      band gap narrower, thus enhancing the absorption of visible light. Compared with 
      pure ZnS, the degradation rates of 2,4-dichlorophenol (2,4-DCP) and tetracycline 
      (TC) by N/Cu-ZnS under visible light (>420 nm) are increased by 83.7 and 51 
      times, respectively. In this research, a promising photocatalyst for 
      photocatalytic degradation of organic pollutants in wastewater is provided.
