Nature Communications, Published online: 14 May 2026; doi:10.1038/s41467-026-72954-z Electrocatalyst degradation driven by oxidation is a major barrier to a sustainable energy society. Here, the authors study the oxidation of Pt(111), a prominent model system, under oxygen evolution conditions, resolving self-limiting layer-by-layer growth of a sub-nanometer disordered PtO2 film.
