Abstract
Abstract Valence tuning of transition metal oxides is an effective approach to design high‐performance catalysts, particularly for the oxygen evolution reaction (OER) that underpins solar/electric water splitting and metal‐air batteries. Recently, high‐valence oxides (HVOs) are reported to show superior OER performance, in association with the fundamental dynamics of charge transfer and the evolution of the intermediates. Particularly considered are the adsorbate evolution mechanism (AEM) and the lattice oxygen‐mediated mechanism (LOM). High‐valence states enhance the OER performance mainly by optimizing the e g ‐orbital filling, promoting the charge transfer between the metal d band and oxygen p band.…
