Abstract

In this study, g-C₃N₄ with boosted photocatalytic CO₂ reduction was obtained through treatment of g-C₃N₄ by NaClO. The strong oxidation ability of NaClO induces enriched carbon vacancies in g-C₃N₄, increases the active sites, optimizes the band structure of g-C₃N₄, and significantly improves the separation efficiency of photogenerated carriers. Photocatalytic activity of the 25 NCN sample is 4.07 times of that of the reference g-C₃N₄. The strategy in this presentation provides a green and convenient reference for treatment of g-C₃N₄ to offer highly efficiency photocatalyst for dual carbon strategy.

NaClO处理富碳空位g-C3N4光催化CO2还原

本研究通过NaClO处理g-C3N4，得到了光催化CO2还原能力增强的g-C3N4。NaClO的强氧化能力使g-C3N4中碳空位富集，活性位点增加，优化了g-C3N4的能带结构，显著提高了光生载体的分离效率。25 NCN样品的光催化活性是参考g-C3N4的4.07倍。该策略为g-C3N4的处理提供了绿色便捷的参考，为双碳策略提供了高效的光催化剂。

期刊介绍： Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage. Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
