Regulation of Oxide Pathway Mechanism for Sustainable Acidic Water Oxidation
Nankai University · Collaborative Innovation Center of Chemical Science and Engineering Tianjin
Abstract
The advancement of acid-stable oxygen evolution reaction (OER) electrocatalysts is crucial for efficient hydrogen production through proton exchange membrane (PEM) water electrolysis. Unfortunately, the activity of electrocatalysts is constrained by a linear scaling relationship in the adsorbed evolution mechanism, while the lattice-oxygen-mediated mechanism undermines stability. Here, we propose a heterogeneous dual-site oxide pathway mechanism (OPM) that avoids these limitations through direct dioxygen radical coupling. A combination of Lewis acid (Cr) and Ru to form solid solution oxides (CrxRu1–xO2) promotes OH adsorption and shortens the dual-site distance, which facilitates the formation of *O radical…
