Cobalt–iron–lead oxide electrocatalysts show promise for the low-pH oxygen evolution reaction—an essential reaction in proton-exchange water electrolysis—but can suffer from corrosion. This study uncovers that the mechanism of cobalt site corrosion is decoupled from the oxygen evolution reaction, paving the way for more stable catalyst designs.
