Semiconductor-based photocatalytic reactions are a practical class of advanced oxidation processes (AOPs) to address energy scarcity and environmental pollution. By utilizing solar as clean, abundant, renewable source, this process offers numerous advantages, including high efficiency, eco-friendliness, low cost. In review, we present several methods construct various photocatalyst systems with excellent visible light absorption efficient charge carrier separation ability through the optimization materials design reaction conditions. Then it introduces fundamentals photocatalysis in both clean generation remediation. other parts, introduce approaches enhance activity by applying different strategies, semiconductor structure modification (e.g., morphology regulation, co-catalysts decoration, doping, defect engineering, surface sensitization, heterojunction construction) tuning optimizing conditions (such concentration, initial contaminant pH, temperature, intensity, charge-carrier scavengers). Then, comparative study on performance recently examined photocatalysts applied production remediation will be discussed. To realize these goals, H2 via water splitting, CO2 reduction value-added products, dye, drug photodegradation lessen toxic chemicals, presented. Subsequently, report dual-functional for simultaneous pollutant reactions. brief discussion about industrial economical applications is described. The follows introducing application artificial intelligence machine learning selection an innovative issues. Finally, summary future research directions toward developing significantly improved efficiency stability provided.

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.
