Understanding of Oxygen Redox in the Oxygen Evolution Reaction

Advanced Materials, Journal Year: 2022, Volume and Issue: 34(50)

Published: July 20, 2022

The electron-transfer process during the oxygen evolution reaction (OER) often either proceeds solely via a metal redox chemistry (adsorbate mechanism (AEM), with bands around Fermi level) or an (lattice oxidation (LOM), level). Unlike AEM, LOM involves instead of redox, which leads to formation direct oxygen-oxygen (OO) bond. As result, such is able bypass rate-determining step, that is, OO bonding, in highlights critical advantage as compared conventional AEM. Thus, it has been well reported LOM-based catalysts are demonstrate higher OER activities AEM-based catalysts. Here, comprehensive understanding and all documented possible characterization techniques can be used identify reviewed.

Oxygen Evolution/Reduction Reaction Catalysts: From In Situ Monitoring and Reaction Mechanisms to Rational Design

Chemical Reviews, Journal Year: 2023, Volume and Issue: 123(9), P. 6257 - 6358

Published: March 21, 2023

The oxygen evolution reaction (OER) and reduction (ORR) are core steps of various energy conversion storage systems. However, their sluggish kinetics, i.e., the demanding multielectron transfer processes, still render OER/ORR catalysts less efficient for practical applications. Moreover, complexity catalyst–electrolyte interface makes a comprehensive understanding intrinsic mechanisms challenging. Fortunately, recent advances in situ/operando characterization techniques have facilitated kinetic monitoring under conditions. Here we provide selected highlights mechanistic studies with main emphasis placed on heterogeneous systems (primarily discussing first-row transition metals which operate basic conditions), followed by brief outlook molecular catalysts. Key sections this review focused determination true active species, identification sites, reactive intermediates. For in-depth insights into above factors, short overview metrics accurate characterizations is provided. A combination obtained time-resolved information reliable activity data will then guide rational design new Strategies such as optimizing restructuring process well overcoming adsorption-energy scaling relations be discussed.
