Summary: Constructing photocatalysts with excellent visible light utilization efficiency and high-efficiency photo-generated charge transfer rate is crucial for the photodegradation of organic pollutants in wastewater. In this study, oxygen-doped graphitic carbon nitride (g-C3N4) was prepared and used as a responsive material for a wide range of visible light. CdS nanoparticles were then anchored onto the g-C3N4 to form a Z-scheme heterojunction, which facilitated interfacial charge separation. The results showed that the oxygen-doped g-C3N4/CdS-3 displayed a significantly higher degradation rate for 2-chlorophenol compared to g-C3N4.

Summary: This study investigates the photocatalytic activity of magnetic CoFe2O4/g-C3N4/ZnO (CF-gCN/ZnO) nanocomposite as a visible-light photocatalyst. The heterojunction CF-gCN/ZnO photocatalyst achieved a photodegradation efficiency of 89% for degradation of methylene blue (MB) after 100 min of irradiation. The formation of heterojunction structures at the interface of g-C3N4 and ZnO leads to improved photocatalytic activity due to the separation of the photo-generated electron-hole pairs.

Summary: The research team synthesized a highly crystalline graphitic carbon nitride homojunction by calcination of a mixture of NH4SCN and urea, using NaCl/KCl molten salts as the preparation medium. The homogeneity of the liquid precursor ensured an intimate homojunction interface, facilitating the charge separation, and the highly crystalline bulk structure built a highway for rapidly transferring charge to the surface. As a result, bulk charge recombination was suppressed, and the spatial separation and transfer efficiency of charges were significantly improved. Compared to low crystalline homojunctions, this highly crystalline homojunction showed 15 times higher activity for the selective photocatalytic oxidation of benzyl alcohol to benzaldehyde. This work provides a simple strategy to construct a highly crystalline graphitic carbon nitride homojunction for solar energy conversion.
