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

Robust Covalent Organic Frameworks for Photosynthesis of H₂O₂: Advancements, Challenges and Strategies

Small, Journal Year: 2024, Volume and Issue: 20(44)

Published: July 6, 2024

Abstract Since 2020, covalent organic frameworks (COFs) are emerging as robust catalysts for the photosynthesis of hydrogen peroxide (H 2 O ), benefiting from their distinct advantages. However, current efficiency H production and solar‐to‐chemical energy conversion (SCC) remain suboptimal due to various constraints in reaction mechanism. Therefore, there is an imperative propose improvement strategies accelerate development this system. This comprehensive review delineates recent advances, challenges, utilizing COFs photocatalytic production. It explores fundamentals challenges (e.g., oxygen (O ) mass transfer rate, adsorption capacity, response sunlight, electron‐hole separation efficiency, charge selectivity, desorption) associated with process, well advantages, applications, classification, preparation purpose. Various enhance performance highlighted. The aims stimulate further advancements discusses potential prospects, application areas field.

Sulfur-Vacancy-Modified Znin2s4/Tppa-1 S-Scheme Heterojunction with Enhanced Internal Electric Field for Boosted Photocatalytic Hydrogen Production

Published: Jan. 1, 2024

The construction of S-scheme heterojunction is an effective approach to accelerate photocarrier transfer and improve charge utilization, thus promoting photocatalytic hydrogen evolution. Herein, we report, for the first time, a based on sulfur-vacancy-modified ZnIn2S4 (Sv-ZIS) covalent organic frameworks (COFs), by in-situ growth Sv-ZIS COF TpPa-1 (composed 1,3,5-triformylphloroglucinol p-phenylenediamine). Under visible-light irradiation, in absence cocatalyst, optimal Sv-ZIS/TpPa-1 (5:1) (with Sv-ZIS: mass ratio 5:1) achieved enhanced production rate 2745 μmol g−1 h−1 than parent ZIS/TpPa-1 (5:1), with AQE 4.67% at 420 nm. Theoretical calculations confirmed that sulfur-vacancy enlarged internal electric field (IEF) Sv-ZIS/TpPa-1, leading greater interfacial from ZIS TpPa-1. IEF rapid separation photocarriers following mechanism synergistically guaranteed improved performance.
