What Makes On‐Chip Microdevices Stand Out in Electrocatalysis?

Abstract

AbstractClean and sustainable energy conversion and storage through electrochemistry shows great promise as an alternative to traditional fuel or fossil‐consumption energy systems. With regards to practical and high‐efficient electrochemistry application, the rational design of active sites and the accurate description of mechanism remain a challenge. Toward this end, in this Perspective, a unique on‐chip micro/nano device coupling nanofabrication and low‐dimensional electrochemical materials is presented, in which material structure analysis, field‐effect regulation, in situ monitoring, and simulation modeling are highlighted. The critical mechanisms that influence electrochemical response are discussed, and how on‐chip micro/nano device distinguishes itself is emphasized. The key challenges and opportunities of on‐chip electrochemical platforms are also provided through the Perspective.
