Abstract Aseries of 0D/2D Bi₂S₃/g-C₃N₄ based heterojunctions were synthesized via one-step hydrothermal processing using Bi(NO₃)₃·5H₂O as bismuth source, sodium thiosulfate as sulfur source, in the present of g-C₃N₄ nanosheets. The as-obtained photocatalysts were characte-rized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV-Vis diffuse reflectance spectra (UV-Vis), photoluminescence spectra (PL) and electrochemical analytic method. The photocatalytic activity of Bi₂S₃/g-C₃N₄ samples was evaluated by the degradation of Rhodamine-B. As a result, the tiny 0-dimentio-nal Bi₂S₃ nanoparticles were well-dispersed on the 2-dimentional g-C₃N₄ nanosheets. And the heterojunctions show higher photocatalytic performance because of the large absorption visible light area, and the increased electron/hole separation rate. The Bi₂S₃/g-C₃N₄heterojunctions also show good stability and high photocatalytic performance after 5 cycle tests.

Key words： Bi₂S₃/g-C₃N₄ heterojunction Rhodamine-B photocatalytic performance
