Summary: This study thoroughly examines the photocatalytic activity of g-C3N4/Fe3O4/ZnO, g-C3N4/Fe3O4, and g-C3N4 catalysts under visible light. The g-C3N4/Fe3O4/ZnO nanocomposite outperforms the other catalysts in terms of degradation efficiency due to the formation of an interface between g-C3N4 and ZnO, which enhances the response to visible light and facilitates the separation of photo-induced electrons and holes. Furthermore, the inclusion of Fe3O4 phase in the nanocomposite addresses the challenge of catalyst recovery and magnetic separation.

Summary: In this study, a Cu-ZnO/g-C3N4 nanocomposite was synthesized and used to fabricate photocatalytic cement mortars. The bactericidal properties of the photocatalytic mortars were explored, and it was found that the nanocomposite had enhanced visible light energy harvesting and exhibited excellent stability. The sterilizing efficiency of the photocatalytic cement mortars increased with an increasing content of the nanocomposite, and the proposed bactericidal mechanism involved photogenerated holes (h(+)) and O-2(-) radicals as the main active species.

Summary: A Z-scheme LaFeO3/g-C3N4/ZnO heterojunction photocatalyst with large specific surface and low cost was synthesized by a glucose-assisted hydrothermal method. The catalyst showed enhanced visible light absorption and carrier separation efficiency, leading to efficient degradation of phenol. The proposed Z-scheme LaFeO3/g-C3N4/ZnO photocatalytic reaction mechanism provides a more economical and efficient concept for phenol degradation.

Summary: The sulfate radical-based advanced oxidation process (SR-AOPs) using peroxydisulfate (PDS) as oxidant has shown great potential in removing persistent organic compounds in water. A Fenton-like process with PDS activation under visible light has been successfully constructed for the efficient removal of organic pollutants. The synthesized g-C3N4@SiO2 photocatalyst exhibited excellent performance in removing Rhodamine B, achieving a removal rate of 96.08% within 50 minutes.

Summary: ZnO/g-C3N4 composite photocatalyst is prepared by ultrasonic dispersion method for Rhodamine B (RhB) degradation from wastewater. The ZnO/g-C3N4 showed enhanced photocatalytic activity due to the heterojunction between ZnO and g-C3N4, which promoted the effective separation of photogenerated carriers. The photocatalytic degradation mechanism of RhB conformed to the S-scheme mechanism combined with DFT calculation.

Summary: A graphitized carbon nitride (g-C3N4)/tungsten nitride (W2N3) heterostructure was successfully synthesized without using any catalysts and templates through high temperature calcination method. The prepared g-C3N4/W2N3 heterostructure exhibited excellent photocatalytic performance under visible light irradiation. Characterization results showed that W2N3 nanosheets were coated on g-C3N4 nanosheets. The heterostructure of W2N3 and g-C3N4 enhanced the absorption capacity of visible light and promoted the photocatalytic activity of methyl orange (MO) by separating photogenerated electron hole pairs.
