Enhanced Oxygen Coupling via Regulated Interfacial Water and *OH Adsorption by Cr─O─Ir Motif to Enable Efficient Acidic Water Oxidation.
Highly active and durable anode electrocatalysts are crucial for acidic oxygen evolution reaction (OER) in proton exchange membrane water electrolyzers (PEMWE), yet IrO2-based catalysts often face a trade-off between activity and stability. In this study, a Cr-IrO2 catalyst is developed through partial substitution of...
