Summary: With the rapid development of economy and modern industry, serious environmental pollution and energy shortage have become major urgent challenges to the human society. Photocatalysis is a promising technology to provide green energy. However, the limitations of g-C 3 N 4 , such as fast recombination of charges, limited light response range, and weak oxidation ability, restrict its photocatalytic performance. The construction of heterojunctions with g-C 3 N 4 and other semiconductor materials can effectively address these issues and improve the photocatalytic performance.

Summary: Co3O4 nanosheet/g-C3N4 hybrids, with the optimized hybrid of 20 wt % g-C3N4 (20-CNCo) displaying the best photocatalytic performances for H-2 evolution, with an average H-2 evolution rate of 134.6 mu mol center dot g(-1)center dot h(-1). The enhanced photocatalytic H-2 evolution activities of 20-CNCo were attributed to the formation of heterojunctions between Co3O4 nanosheets and g-C3N4, increasing optical absorption ability, promoting charge separation, accelerating electron transfer, and prolonging excited electrons' lifetime. The unique S-scheme charge transfer mechanism retained strong redox ability, contributing to H-2 evolution. This work provides strategies for designing active catalysts for photocatalytic reactions.

Summary: Researchers fabricated a S-scheme heterojunction photocatalyst by coupling TiO2 with three dimensionally ordered macroporous sulfur-doped graphitic carbon nitride (3DOM SCN/T) through electrostatic self-assembly. The optimized photocatalyst achieved a high activity in photocatalytic H2O2 production without the addition of hole scavengers. The outstanding performance can be attributed to the synergy between the 3DOM framework and the S-scheme heterojunction. Finally, a proposed mechanism of photocatalytic H2O2 production over the 3DOM SCN/T S-scheme composite is presented. This work provides novel insights into the development of efficient photocatalysts for H2O2 production from water and O2.

Summary: This study synthesized hydrophilic polypyrrole and graphitic carbon nitride decorated zinc oxide nanorod arrays as a photoanode, which exhibited enhanced performance and stability for photoelectrochemical water splitting. The modified g-C3N4 nanosheets broadened the light absorption range and suppressed the recombination of photogenerated charges, while the polypyrrole coating layer inhibited the dissolution and corrosion of zinc oxide nanorods and facilitated the separation and transfer of photogenerated charge carriers. The hydrophilic surface of the photoanode provided a large electrochemically active surface area for efficient charge/mass transfer.

Summary: This study investigates the design and synthesis of well-designed 2D graphene oxide-modified polymeric graphitic carbon nitride composite nanosheets (GO/g-C3N4) as sensitizers and catalytic substrates to enhance the visible light-driven photocatalytic performance of ZnO-based photocatalysts. The combination of ultrasonic and hydrothermal methods is used to prepare 2D GO/g-C3N4 composite nanosheets and they are then coupled with ZnO nanoparticles to form ternary GO/g-C3N4-ZnO heterojunction composites. The resulting nanocomposites exhibit significant improvements in visible light photocatalytic activity compared to pure ZnO and other composites, attributed to the enhanced electronic interaction and efficient transfer of photogenerated electrons. Moreover, the increase in GO loading in GO/g-C3N4 composite nanosheets leads to wider light absorption range, fluorescence quenching, excellent optical response, and good stability.

Summary: Substantial improvement is needed in efficient and affordable decolorization and disinfection methods for water and wastewater. Cobalt-doped tin oxide nanoparticles (NPs) and cobalt-doped tin oxide/sulfur-doped graphitic carbon nitride nanocomposites (NCs) were synthesized and used for the photocatalytic degradation of methylene blue and the disinfection of bacteria under sunlight. The Co-SnO2/50% SGCN NCs exhibited the highest efficiency in both methylene blue degradation and bactericidal action. This research suggests that Co-SnO2/50% SGCN NCs have the potential to be utilized as a dual-functional material for water treatment.

Summary: In this study, a composite electrode composed of Ti/TiH2/beta-PbO2_Mn3O4@C was fabricated and investigated for zinc electrowinning. The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
