Summary: This study proposes a facile method to synthesize an efficient photocatalytic material, CNZn heterojunction, for the degradation of sulfonamides. The optimized CNZn heterojunction exhibited significantly higher degradation efficiency for sulfamethoxazole compared to g-C3N4 and ZnO alone. The study also reveals the photodegradation mechanism of sulfamethoxazole and proposes a possible mechanism for enhanced degradation using a CNZn heterojunction photocatalyst.

Summary: A Z-scheme mesoporous BiVO4/g-C3N4 nanocomposite heterojunction was synthesized with high surface area and crystallinity for efficient visible light-driven photocatalysis of Hg(II) ions. The nanocomposite showed enhanced photoreduction efficiency compared to pristine materials, with the 1.2% BiVO4/g-C3N4 nanocomposite achieving the highest performance. This enhancement was attributed to reduced carrier recombination and improved utilization of visible light, as confirmed by various analyses.

Summary: The use of graphitic nitride (g-C3N4) in visible light responsive photocatalysis has gained significant attention in water treatment. Carbon doping has been shown to enhance the photocatalytic activity of g-C3N4. In this study, g-C3N4 was modified with barbituric acid and further treated with reduced graphene oxide and used for the inactivation of ofloxacin-resistant bacteria under UVA-visible wavelength. The results showed that the modified g-C3N4 exhibited strong photocatalytic activity and effectively inactivated the bacteria. Reactive oxygen species played a dominant role in the inactivation process, causing oxidative stress and damage to the cell membrane. This research provides valuable insights into the use of rGO modified g-C3N4 for the inactivation of bacteria under visible light radiation.

Summary: In this study, an ultrathin layered 2D/2D heterojunction catalyst ReS2/CCN was successfully constructed, which exhibited excellent photocatalytic performance with a high H-2 evolution rate under visible light irradiation. The efficient charge transport of highly crystalline CCN, the strong visible light harvesting of ReS2 nanoflakes, and the synergistic effect of the ultrathin layered 2D/2D heterojunction are the main reasons for its enhanced performance.

Summary: In this work, holey ultrathin g-C3N4 nanosheets (HCN NSs) with rich active sites were prepared, followed by the growth of 1T-MoS2 NSs on their surfaces to construct 2D/2D 1T-MoS2/HCN heterostructure. The hybrid with 8 wt% 1T-MoS2 content (1T-MoS2/HCN-4) exhibited the highest H2 production rate of 2724.2 mmol-1 h-1 g-1 under simulated solar light illumination with an apparent quantum efficiency of 8.1% (l=370 nm). Moreover, the 1T-MoS2/HCN-4 hybrid showed improved stability after a long-time test. This study paves the way for the design of highly-efficient g-C3N4 based 2D/2D heterostructures for photocatalytic H2 production.

Summary: A nanocomposite consisting of CoFe-layered double hydroxides grown on graphitic carbon nitride nanosheets (CoFe-LDH/g-C3N4) has been successfully synthesized and exhibits significant photocatalytic activity for the degradation of tetracycline. The enhanced performance is attributed to the intimate interfacial contact, enlarged surface area, broadened absorbance range, and improved electron transfer. This study demonstrates the feasibility and potential application of the nanocomposite for the removal of tetracycline from contaminated water.
