Summary: This study presents an interface engineering strategy to co-integrate isotype and p-n heterojunctions, enabling the fabrication of g-C3N4/g-C3N4 nanohybrids. The coherent boundary between the two phases of g-C3N4 allows for intimate 2D interfacial contact through pi-pi stacking interactions. The resulting composite exhibits strong redox ability, efficient exciton dissociation, and desirable optoelectronic characteristics, highlighting the significance of interface engineering for photocatalytic enhancement.

Summary: This study presents a novel and cost-effective photocatalytic system using CdS-NRs/g-C3N4 nanohybrid with Co and Ni as cocatalysts to accelerate solar-assisted water-splitting reaction efficiently. The dual cocatalysts selectively shuttle electrons and holes away from the semiconductor surface, leading to high H-2 production rate, turnover number, and external quantum yield. The synergistic effect between the cocatalysts and the heterojunction provides more active sites for water splitting, demonstrating the promising potential of using dual cocatalysts for improving photocatalytic water splitting systems.

Summary: The properties and interactions of g-C3N4, Bi3NbO7, and g-C3N4/Bi3NbO7 photocatalysts were revealed through various tests. g-C3N4/Bi3NbO7 has a lower band gap and higher absorption of visible light, as well as higher efficiency in separating photogenerated electron-hole pairs. In the photocatalytic reduction of Cr(VI), g-C3N4/Bi3NbO7 is more effective than pure g-C3N4 and Bi3NbO7.

Summary: Graphitic carbon nitride (CN) coupled with microcrystalline cellulose (MCC) (MCC-X/CN) exhibits excellent photocatalytic performance for tetracycline (TC) degradation and H-2 evolution. The optimized MCC-0.05/CN shows significantly improved TC degradation rate and H-2 evolution rate compared to pure CN. This improvement is primarily attributed to the hydrogen bonding (H-bonding) between CN and MCC, enabling excellent charge separation and migration.

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: Researchers fabricated 3D interconnected porous boron doped polymeric g-C3N4 catalysts with efficient photocatalytic activity for hydrogen evolution and dye contaminant elimination under visible-light irradiation. The as-fabricated catalysts exhibited significantly enhanced hydrogen evolution (4.37 mmol g-1 h-1) and RhB contaminant elimination (96.37%) activity. The 3D interconnected structure and B-doping have a synergistic effect on the greatly improved photocatalytic activity, providing a higher specific surface area and abundant active sites for enhanced absorption and separation of photogenerated carriers.
