The novel visible light-induced carbon nitride/carbon dots (g-C3N4/CDs) composites were successfully synthesized by introducing CDs into polymeric g-C3N4. The structures and optical properties of composites were characterized by XRD, FT-IR, SEM, TEM, DRS, respectively. For the degradation of rhodamine B (Rh B), the g-C3N4/CDs composites exhibited significantly higher visible light photocatalytic activity than that of a single semiconductor. The optimal percentage of CDs was 50%. In addition, the stability of the prepared composites in the photocatalytic process was also investigated. The enhanced photocatalytic performance could be due to the high separation efficiency of the photogenerated electron–holes pairs. The possible photocatalytic mechanism of g-C3N4/CDs was proposed to guide the further improvement of their photocatalytic activity.
