Multifunctional Roles of Ionic Microenvironments in the Preparation, Modification, and Application of g‐C₃N₄

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 7, 2025

Abstract As a visible light‐responsive metal‐free polymer semiconductor, graphitic carbon nitride (g‐C 3 N 4 ) has garnered increasing attention in photocatalysis but needs structural modification and functional enhancement. Recently, the rational design of ionic microenvironments (IMEs) by leveraging tunability various ions to endow catalysts with tailored functionalities been elevated hot direction. To elucidate their respective effects on g‐C , IMEs are categorized into three types, namely plasma IMEs, organic inorganic according criteria external field dependence, cation type, application scenarios. These promotions include facilitated preparation, diversified modifications, improved efficiencies. First, participate constructing functionalized microenvironment through dynamic interactions precursor during facilitating customization, crystal nucleation growth, surface performance enhancement, process cleanliness. Second, create tunable for post‐modification functioning as an electron reservoir, modifier, substrate adsorbent, stabilizer. Lastly, synergistic effect between IME they achieve targeted product regulation, enhanced chemical stability, efficient adsorption, potential fields like catalysis, energy storage, gas adsorption. Also, limitations, challenges, prospects strategies discussed, offering systematic insights IMEs‐based structure‐activity relationships 4.
