Self-assembled monolayers (SAMs) have emerged as a transformative interfacial engineering platform. Their nanoscale thickness, customizable molecular structures, and spontaneous chemical anchoring allow for precise work-function tuning, effective defect passivation, and controlled perovskite crystallization. As SAMs continue to set efficiency records in small-area lab devices, adapting these molecular layers for large-area, high-throughput industrial processing has become the vital step toward commercial deployment. Therefore, a thorough review bridging molecular design, interfacial mechanisms, and large-scale manufacturability is urgently required. Herein, we systematically review recent progress in SAM-based contacts for PSCs. We detail the tripartite architecture of anchoring, spacer, and tail groups, unravel mechanisms governing energy alignment and passivation, map the structural evolution from carbazole monomers to polymeric systems, and assess scalable coating protocols for large-area modules. This review provides essential scientific and practical guidelines to bridge laboratory research and industrial-scale manufacturing for perovskite photovoltaics.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"11 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149173132","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}

Recent studies are starting to overturn this view. Curved gas–liquid interfaces can behave as electrified microreactors. Here, electrified is used broadly to include interfaces charged by external polarization, spontaneous interfacial charging, or contact electrification. Their charge accumulation, asymmetric solvation, and local electric fields have been linked to altered ion activities, apparent redox potentials, and reaction pathways that are otherwise unfavorable in bulk water. Bubble chemistry has been reported in hydrogen peroxide generation, pollutant removal, nitrogen fixation, methane oxidation, and carbon dioxide reduction, often without an added conventional catalyst or with low-material-input conditions. This Review organizes these developments into four regimes: pinned bubble coronas at biased solids, dispersed micro- and nano-bubbles in bulk water, curvature-amplified gas–liquid interfaces, and bubble-mediated carbon and nitrogen transformations. The outstanding challenge is no longer whether bubbles are reactive, but how interfacial electric fields, ion gradients, confined liquid films, and radical pathways can be measured, separated, and scaled without losing selectivity. The emerging design principle is to engineer bubbles as reaction phases, rather than treating them merely as losses. Coupling bubble interfaces with electrochemical, photochemical, and contact-electrification strategies may turn them into controllable elements of sustainable chemistry.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"3 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149173127","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}

Two-dimensional (2D) material-supported single-atom catalysts (SACs) address this challenge through atomically defined coordination environment that enable precise tuning of the critical *COOH and *CO adsorption energies, the two descriptors that simultaneously govern CO2 activation and HER suppression. This review examines the convergence of 2D-SAC design and machine learning (ML) for CO2RR catalyst discovery. We first outline the mechanistic foundations of CO₂RR together with comparative insights from HER and OER, then discuss the structural and electronic principles governing single-atom stabilisation on nitrogen-rich carbon, transition metal dichalcogenide, and MXene supports. Recent catalytic advances are assessed with CO2RR as the primary focus, including proximity-engineered systems that promote C-C coupling and multicarbon product formation. Finally, emerging ML frameworks are critically reviewed, covering electronic, geometric, and spectroscopic descriptor design, data source strategies, and high-throughput screening workflows. Operando ML integration has revealed the dynamic evolution of active sites under reaction conditions, fundamentally reframing how training datasets must be constructed. Key priorities identified for the field are large-scale CO2RR-specific SAC database construction, multi-target descriptor development for full product selectivity, and closure of the synthesis-prediction feedback loop.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"20 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149173138","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}

Electrocatalytic methane conversion, driven by clean electrical energy, enables the selective transformation of methane under mild conditions, offering a promising alternative to conventional energy-intensive and high-emission processes. This review systematically summarizes recent advances in the electrocatalytic conversion of methane into high-value-added products. The article begins by explaining the fundamental principles of electrocatalytic methane conversion and highlighting its distinct advantages over conventional methods. Subsequently, we focus on a variety of target products, including C1 products, C2+ products, and other high-value products, offering a detailed discussion of the latest developments in diverse electrocatalytic systems and providing an in-depth analysis of their respective reaction mechanisms. Finally, the review will conclude by identifying the key scientific and technological challenges currently faced by this field and by proposing perspectives on future research directions and development opportunities, with the aim of serving as a valuable resource for advancing this emerging area even further.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":" ","pages":""},"PeriodicalIF":4.3,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149177824","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}
