The poor activity and stability of electrode materials for the oxygen evolution reaction (OER) are the main bottlenecks in the water splitting reaction for H2 production. Here, by studying activity
stability trends for the OER on conductive M1OxHy, Fe-M1OxHy and Fe-M1M2OxHy
hydr(oxy)oxide clusters (M1= Ni, Co, Fe; M2= Mn, Co, Cu), we show that balancing the rates of
Fe dissolution and redeposition over a MOxHy host establishes dynamically stable Fe active sites.
Together with tuning the Fe content of the electrolyte, the strong interaction of Fe with the
MOxHy host is the key to control the average number of Fe active sites present at the solid-liquid
interface. We suggest that the Fe-M adsorption energy can therefore serve as a reaction
descriptor that unifies OER catalysis on 3d transition metal hydr(oxy)oxides in alkaline media.
Thus, introduction of dynamically stable active sites extends the design rules for making active
and stable interfaces.
