Metal‐Free Modification Overcomes the Photocatalytic Limitations of Graphitic Carbon Nitride: Efficient Production and In Situ Application of Hydrogen Peroxide

Advanced Energy Materials, Journal Year: 2024, Volume and Issue: 14(39)

Published: July 22, 2024

Abstract Graphitic carbon nitride (g‐C 3 N 4 ) assisted photocatalytic production of hydrogen peroxide (H 2 O has already attracted the interest many researchers due to its environmental sustainability. Nevertheless, inherent drawbacks g‐C limit progress. Metal‐free modification strategies, including nanostructure design, defect introduction, doping, and heterojunction construction, have been developed improve efficiency H production. Compared metal modification, metal‐free strategies avoid use precious metals leaching heavy ions, which advantages good stability friendliness. However, a comprehensive review from modified by is still lacking. This first recaps mechanism , photoexcitation, carrier separation redox reactions. Then, perspective advances in photocatalysts are presented, with special focus on kernel connection between different based pivotal stages Subsequently, recent applications ‐based for situ generated mainly water purification organic synthesis, briefly discussed. Finally, prospects envisioned hope that it will “something do” field
