Preprint of "Cobalt Oxidation State Controls Ir–CoOₓ Catalysts for Acidic Oxygen Evolution: From Model Surfaces to PEM Water Electrolyzers"

Water electrolysis is a key technology for sustainable hydrogen production, yet its efficiency in proton exchange membrane (PEM) electrolyzers is limited by the sluggish oxygen evolution reaction (OER) and the high cost of iridium-based catalysts. Combining Ir with Co and its oxi...
