Secondary thermal exfoliation is an effective method to synthesize 2D carbon nitride nanosheets (CNN). Further broadening the visible light response and optimizing the photoelectric conversion efficiency are effective strategies to improve the photocatalytic performance of CNN materials. In this work, we report thiophene-ring doped carbon nitride nanosheet photocatalysts (CNN-Th_x) prepared from in situ polymerization doping and secondary thermal exfoliation using 2-aminothiophene-3 -carbonitride as the molecular doping source. Thiophene-ring with excellent chemical properties was stably doped into conjugated CNN nanosheets. After secondary thermal exfoliation, the products maintained 2D hybrid conjugated polymer structures, and the thiophene-ring was still stably doped in the CNN conjugated heterocyclic skeleton. Thiophene-ring doping causes the further expansion of the π-conjugated system, reduces the bandgap, broadens the visible light absorption range, and accelerates the photoelectric conversion efficiency of the catalysts. At the same time, thermal exfoliation cooperated with thiophene doping leads to a more significant n-π^* transition, which greatly improves the photocatalytic activity of the catalysts. The results showed that CNN-Th_x had significantly enhanced photocatalytic reduction performance, in which the H₂ evolution activity of CNN-Th₁₀ reached 322.8 μmol·h^-1, and the generated H₂O₂ concentration reached 223.1 μmol·L^-1 after 4 h, which were 3.6 and 22.3 times that of CNN, respectively.
