However, by repeating these measurements using EIS, we clarify that these anomalous <em>C</em><sub>dl</sub> trends are not measurement artefacts but instead reflect intrinsic properties of the Pt(111)/HClO<sub>4</sub> interface, necessitating continued investigation. We further highlight the complexity introduced by electrosorbed H<sub>ads</sub> and/or OH<sub>ads</sub> species resulting from catalytic H<sub>2</sub>O dissociation, which contribute an adsorption (pseudo)capacitance, <em>C</em><sub>ads</sub>. This complicates the deconvolution of <em>C</em><sub>dl</sub> from total capacitance, a challenge further exacerbated by structure-dependent adsorption between different Pt facets.

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}
