This review highlights recent advances in electrochemical sensing technologies and their potential as field-deployable devices for rapid screening and on site PFAS detection. Examples include sensor platforms based on redox-active reporters, molecularly imprinted polymers (MIPs), redox dyes, metal organic frameworks (MOFs), covalent organic frameworks (COFs), nanoparticle impacts, and nanobubble and nanopore technologies, coupled with direct or indirect signal transduction strategies.

While extensive efforts have focused on catalyst design and electrolyte composition, the role of the interfacial water properties, an often-overlooked parameter, has only recently come under investigation. Water serves as the primary proton donor (in aqueous electrolytes) in the absence of hydronium, which can influence the competition between CO<sub>2</sub>RR and the hydrogen evolution reaction (HER). Despite studies dating back to the 1980s demonstrating that electrolyte composition significantly impacts CO<sub>2</sub>RR performance, the effects of the electrolyte composition on the interfacial water properties have remained largely unexplored. Recent findings suggest that tuning the interfacial water properties can influence C–C coupling by altering solvation environments and stabilize reaction intermediates. This perspective explores how tuning the interfacial water properties improves C–C coupling, providing a new strategy for improving catalysis.</div></div>","PeriodicalId":11028,"journal":{"name":"Current Opinion in Electrochemistry","volume":"52 ","pages":"Article 101722"},"PeriodicalIF":7.9,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144614293","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}

This review highlights recent developments in scanning probe microscopy (SPM), including scanning electrochemical cell microscopy (SECCM), electrochemical scanning tunneling microscopy (EC-STM), and electrochemical atomic force microscopy (EC-AFM). These SPM techniques provide complementary insights into nanoparticle size, morphology, electronic structure, and surface reactivity. SECCM enables localized electrochemical analysis with high spatial resolution, while EC-STM and EC-AFM facilitate nanoscale imaging and the identification of active sites involved in electrocatalytic reactions. One of the most promising strategies involves integrating these techniques to establish structure–activity correlations at the single-nanoparticle level, thereby enhancing characterization capabilities. We demonstrate how hybrid characterization techniques can be employed to capture in situ information during complex electrochemical processes at the electrode–electrolyte interface. Specifically, we highlight the monitoring and measurement of local electrochemical processes using high-spatial-resolution imaging in correlation with single-entity electrochemistry techniques.</div></div>","PeriodicalId":11028,"journal":{"name":"Current Opinion in Electrochemistry","volume":"52 ","pages":"Article 101710"},"PeriodicalIF":7.9,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144271840","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}
