Notably, inspired by the recent success in nanoelectronic semiconductor devices, the emerging field of on-chip electrocatalytic microdevices has emerged as a powerful alternative platform to traditional techniques. This unique device configuration offers several advantages, including in situ electronic/electrochemical measurements and adjustable microstructure of individual catalysts, which is constantly expanded to probe electrochemical processes and obtain previously inaccessible information. This review covers recently published work on a range of electrochemical reactions, including hydrogen evolution reaction (HER), oxygen evolution reaction (OER), water splitting, carbon dioxide reduction (CO2RR), oxygen reduction reaction (ORR), and other electrochemical reactions.

As these processes occur on disparate scales, however, bridging the two into a (single) comprehensive reaction model is a challenging task and active area of research. In this perspective, we give a current overview of transport-coupled kinetic models while making a distinction between those that describe the surface reaction <em>via</em> an effective phenomenological or first-principle-based kinetic model. This choice tends to be accompanied by a correspondingly more or less elaborate inclusion of mass transport. The two modeling approaches thus generally differ in the scientific questions that they aim to answer; whether focusing on elaborate transport effects and resulting design rules at the device level or more detailed mechanistic insight on a microscopic scale. We first discuss these approaches separately, including their pros and cons through notable studies in the existing literature and conclude with an outlook view on combining the value of both in future research.</div></div>","PeriodicalId":11028,"journal":{"name":"Current Opinion in Electrochemistry","volume":"49 ","pages":"Article 101631"},"PeriodicalIF":7.9,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143102848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
