Scholarcy highlights

  • CDots/Ag/ZnO photocatalyst had good biocompatibility and low biotoxicity
  • Oxygen defect-rich pencil-like ZnO nanorods were prepared by a simple hydrothermal method, and Ag and CDots co-catalysts were further introduced for modification
  • The morphology, structure, UV–vis diffuse reflectance, photoluminescence and electrochemical properties of the as-prepared photocatalysts were studied by a series of analytical techniques and measurements
  • The results indicated that pencil-like morphology and the existence of oxygen defects increased the carrier concentration and promoted charge carrier separation of ZnO
  • The consequence of the biotoxicity assessment showed that the ternary photocatalyst had good biocompatibility and low biotoxicity
