However, competing pathways and mismatched intermediate kinetics hinder the selective formation of products like urea, amines, and amides. Recent advances reveal that rational modulation of the electrochemical microenvironment can effectively steer reaction pathways and stabilize coupling-relevant intermediates. This review systematically summarizes how microenvironment engineering, originally developed for CO2 and NOx reduction reactions, can be leveraged to enhance C-N coupling efficiency and selectivity. The key strategies are categorized into 1) catalyst-centered design (e.g., ligand coordination, defect engineering, and morphology control), 2) ionic and electrolyte modifications (e.g., cation/pH effects), and 3) dynamic approaches such as pulsed electrolysis. These methods shape local fields, surface coverage, and mass transport properties, ultimately directing reactants toward cross-coupling over competing routes. By drawing parallels with well-established CO2RR/NOxRR systems and showcasing emerging examples in C-N coupling, the central role of microenvironment control is highlighted. Finally, a perspectives on strategies to further improve activity, selectivity, and atom economy in future C-N coupling systems are offered.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e2501366"},"PeriodicalIF":6.6,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144937242","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}

Bismuth-zirconium composite catalysts (Bi-Zr-KB, where KB = Ketjen Black) are developed to leverage Zr incorporation to modulate the local CO2 microenvironment in an alkaline flow-cell system. Among the catalysts synthesized with various Bi/Zr ratios, the Bi-Zr-KB sample with a Bi/Zr ratio of 2 demonstrated the highest performance, achieving a current density of -176 mA cm-2 and a formate Faradaic efficiency of 88% at -0.6 V vs reversible hydrogen electrode; representing a 1.4-fold enhancement over the Bi-only catalyst. Material characterizations (X-ray photoelectron spectroscopy, scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray absorption near edge structure) confirmed the reduction of Bi species to metallic Bi during electrolysis, while Zr remained chemically stable. Electrochemical impedance spectroscopy and in situ Raman spectroscopy revealed that Zr incorporation suppresses local pH rise (≈0.3 units lower), facilitating improved CO2 availability near active sites. Density functional theory calculations using Bi, Bi2O3, and ZrBi models showed interfacial Bi-Zr phases enable uniform CO2 adsorption and enhanced charge transfer across surface orientation. These findings highlight Zr role in modulating catalyst microenvironment to overcome CO2 mass transport limitations and achieve high-rate CO2 conversion to formate.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e2501024"},"PeriodicalIF":6.6,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144937183","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}

Ionic liquids offer a promising alternative to existing sorbents due to their negligible volatility and their tunable properties. Herein, a multifunctional phosphonium triazolate ionic liquid capable of reacting reversibly with CO2 without loss of fluidity through both cation and anion is presented. Using a combination of experiments and reaction models the interplay of different absorption mechanisms is demonstrated at varying temperatures and pressures, which lead to high capacity for CO2 absorption and excellent selectivity for CO2 over CH4. The multifunctional phosphonium triazolate can be used to prepare a porous ionic liquid with enhanced physical gas absorption by dispersing up to 10% w/w of ZIF-8. The stability and porosity are maintained after CH4 absorption but are lost upon prolonged exposure to CO2 due to dissolution of the porous solid. These findings provide crucial insights for the development and modeling of ionic liquid-based absorbents, paving the way for biogas upgrading technologies with reduced carbon footprint.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501347"},"PeriodicalIF":6.6,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144937236","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}

However, the loading effect of conductive active substances and structural design remain critical factors that limit the performance of flexible conductive materials. In this study, polyvinyl alcohol/sodium lignosulfonate (PVA/LS) electrospun films are fabricated and polypyrrole (PPy) particles are loaded onto the surface of the electrospun fibers through in-situ polymerization. By leveraging the abundant sulfonic acid groups in LS, the adsorption force between electrospun fibers and PPy is significantly enhanced. This enhancement ensures the formation of uniform and continuous PPy shell that endows the electrospun film with high conductivity and exceptional electrochemical performance. Furthermore, a stacking method is employed to transform the PVA/LS/PPy film into a three-dimensional thick structure, which significantly increases the areal capacitance. With four layers of stacking, the areal capacitance of the symmetric solid-state supercapacitor assembled by 4(PPy6) reaches 2629.65 mF cm-2, which is an impressive increase by a factor of 4.64 compared to the single-layer PPy6. This work presents a simple yet effective approach for preparing self-supporting flexible conductive materials with fine microstructures. Consequently, it provides valuable insights for performance improvement of flexible energy storage devices.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501236"},"PeriodicalIF":6.6,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144937225","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}

In this framework, water and sunlight are the sustainable sources. Photocatalyst-loaded hydrogel materials have already shown their potential as a water storage and catalyst host matrix for H2 production. This study explores the thin film geometry of such systems to demonstrate the scalability of photocatalysis. Graphitic carbon nitride is used as a catalyst and combined with platinum as a co-catalyst. The resulting catalytic centers are introduced in poly(N-isopropylacrylamide) hydrogel thin films. First, the swelling behavior of the resulting hybrid hydrogels is studied under high relative humidity, and the influence of different catalyst loadings is discussed. Then, time-of-flight neutron reflectometry is used to access the vertical material composition inside the hybrid thin film in the dry state, which shows an enrichment layer of catalyst at the substrate-bulk interface. Operando grazing incidence small-angle neutron scattering displays the microscopic changes happening under heavy water (D2O) vapor and light irradiation. Next, gas chromatography demonstrates the potential of the studied hydrogel films by determining their H2 production rates. The recorded H2 production is correlated to the microstructure analysis and reveals the importance of the observed catalyst enrichment layer.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e2501550"},"PeriodicalIF":6.6,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144937194","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}
