To further improve the photocatalytic activity of polymeric semiconductor, graphitic carbon nitride (g-C₃N₄), for organic degradation, carbonized MoS₂/S-doped g-C₃N₄ heterojunction (MoSC/S-CN) was prepared simply by hydrothermal method. And it was used to degrade rhodamine B (RhB) under visible-light illumination. Based on the results, it turned out that the visible-light adsorption range of optimized MoSC/S-CN became much broader, and the corresponding RhB degradation efficiency under visible-light illumination within 100 min was 92.5%, which was 68.83% higher than that of pure g-C₃N₄. Based on a series of structural and optical characterizations, it is clear that after S doping and further coupling with carbonized MoS₂, MoSC/S-CN shows a synergistic effect. The band structure of g-C₃N₄ changes, and the photo-induced electron-hole pair separation rate is enhanced, which improves the photocatalytic activity of g-C₃N₄ effectively.
