Here, a highly efficient NO3- to NH3 electrocatalyst with single Fe atoms dispersing on graphdiyne (GDY) is constructed through an in-situ growth method. Experimental analysis demonstrates the formation of high-density atomic active sites on GDY, ensuring the high intrinsic activity of the electrocatalyst. Besides, the newly formed sp-C~Fe chemical bonds bridged GDY and Fe atoms provides a well-defined channel for selectively and efficiently transferring electrons from the active sites to the reactants/key intermediates, allowing for the selective NO3- activation and efficient protonation. This atomic-scale electronic modulation enables exceptional nitrate reduction performance, achieving record-high Faradaic efficiency (40.17%) and ammonia yield (106.65 μmol h⁻¹ cm⁻²) while maintaining operational stability.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"9 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143846911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The addition of H₂O enhances both the methane conversion rate and selectivity across all alkali metal salts, which suggests there is an OH-radical-mediated pathway that is facilitated by the surface formation of alkali peroxide. To explain the observed experimental differences, we explored the interactive energetics of alkali–anion pairs with a particular focus on the stabilization of alkali peroxide intermediates by anion species. Anion polarizability is indicative of the alkali ion's degree of freedom and positively correlated with the catalytic performance due to formation capability of catalytic alkali peroxide species. This insight highlights the critical role of the reaction of surface alkali peroxide with H₂O as a key elementary step in OCM.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"24 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143832324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MXene-based composite photocatalysts show great promise, which utilize solar energy for purification. MXenes have excellent electrical conductivity, a large surface area due to their 2D structure, and surface functional groups beneficial for photocatalysis. In this review, various synthesis methods have been developed to prepare MXenes with different properties for specific applications, such as hydrofluoric acid etching, substitutes etching and molten fluoride etching. The influence of different groups on the performance of MXene have been determined. In photocatalytic reactions, modification strategies including heterojunction construction, doping, precious metal deposition and single atom anchor have been explored to enhance the photocatalytic performance of MXene-based composites. It is found that MXenes can act as support that limits photocatalyst size, enhance reactant adsorption, and functions as cocatalyst loaded onto semiconductors to improve charge separation. Our perspectives on the key challenges and future directions of developing high-performance MXene-based composite photocatalysts for environmental application are elaborated.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"121 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143832321","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
