Proton-exchange membrane water electrolysers rely on iridium to catalyse their anodic reaction, and while ruthenium is a less costly alternative due to its similar activity, it is not as stable. Now, a hierarchical machine-learning catalyst discovery workflow, termed mixed acceleration, is put forward to predict catalyst synthesis, activity and stability, and identify promising RuOx-based water oxidation catalysts.
