Enhancing Photosynthesis Efficiency of Hydrogen Peroxide by Modulating Side Chains to Facilitate Water Oxidation at Low‐Energy Barrier Sites

Advanced Materials, Journal Year: 2024, Volume and Issue: 36(18)

Published: Jan. 27, 2024

Abstract Hydrogen peroxide (H 2 O ) is a crucial oxidant in advanced oxidation processes. In situ, photosynthesis of it natural water holds the promise practical application for remediation. However, current H systems primarily relies on oxygen reduction, leading to limited performance with low dissolved or anaerobic conditions found polluted water. Herein, novel photocatalyst based conjugated polymers alternating electron donor–acceptor structures and electron‐withdrawing side chains donors introduced. Specifically, carbazole functions as donor, triazine serves acceptor, cyano acts chain. Notably, exhibits remarkable solar‐to‐chemical conversion 0.64%, highest reported Furthermore, even conditions, achieves an impressive photosynthetic efficiency 1365 µmol g −1 h , surpassing all . This improvement attributed effective relocation active site from high‐energy low‐energy acetylene mediated by chains, resulting enhanced generation breakthrough offers new avenue efficient remediation using technologies oxygen‐limited environments, holding significant implications environmental restoration.

Energy band engineering of graphitic carbon nitride for photocatalytic hydrogen peroxide production

Carbon Energy, Journal Year: 2024, Volume and Issue: 6(11)

Published: July 9, 2024

Abstract Hydrogen peroxide (H 2 O ) is one of the 100 most important chemicals in world with high energy density and environmental friendliness. Compared anthraquinone oxidation, direct synthesis H hydrogen oxygen (O ), electrochemical methods, photocatalysis has characteristics low consumption, easy operation less pollution, broad application prospects generation. Various photocatalysts, such as titanium dioxide (TiO graphitic carbon nitride (g‐C 3 N 4 metal‐organic materials, nonmetallic have been studied for production. Among them, g‐C which are simple to synthesize functionalize, attracted wide attention. The electronic band structure shows a bandgap 2.77 eV, valence maximum 1.44 V, conduction minimum −1.33 theoretically meets requirements In comparison semiconductor materials like TiO (3.2 eV), this material smaller bandgap, results more efficient response visible light. However, photocatalytic activity yield were severely inhibited by electron‐hole pair recombination rate, utilization rate light, poor selectivity products. Although previous reviews also presented various strategies improve production, they did not systematically elaborate inherent relationship between control their structure. From point view, article focuses on engineering latest research progress On basis, strategy production proposed through morphology control, crystallinity defect, doping, combined other strategies. Finally, challenges industrialization discussed envisioned.
