A highly efficient and stable oxygen evolution reaction (OER) plays a key role in the commercialization of proton exchange membrane (PEM) water electrolyzers. Perovskite-derived IrOxHy catalysts have been demonstrated to be highly catalytically active in a harsh acidic environment. On the other hand...
