The Bi₂WO₆/g-C₃N₄ composite photocatalysts were successfully synthesized by implanting Bi₂WO₆ nanoparticles into the interlayer and surface of g-C₃N₄ using a solvothermal method. The prepared samples were characterized by XRD, SEM, TEM, UV-Vis, BET and photogradation of RhBfor comprehensive structural, morphological, specific surface area and visible-light properties. This results show the interlayer structure of g-C₃N₄ was partially peeled and formed Bi₂WO₆/g-C₃N₄ photocatalyst. The 60 wt% Bi₂WO₆/g-C₃N₄ photocatalysts possess enhanced photocatalytic activity than the single phase Bi₂WO₆ and g-C₃N₄ under visible light, which can be ascribe to its wide visible light reponse, large surface area and high quantum efficiency. In addition, the Bi₂WO₆/g-C₃N₄ composite is not only highly stable but also easy to be collected.
