AB  - The poor activity and stability of electrode materials for the oxygen evolution reaction are the main bottlenecks in the water-splitting reaction for H2 production. Here, by studying the activity–stability trends for the oxygen evolution reaction 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 controlling 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 oxygen evolution reaction catalysis on 3d transition-metal hydr(oxy)oxides in alkaline media. Thus, the introduction of dynamically stable active sites extends the design rules for creating active and stable interfaces.

AB  - A remaining challenge for deployment of proton-exchange membrane fuel cells is the
limited durability of Pt-nanoscale materials that operate at high voltages during the
cathodic oxygen reduction reaction. In this work, atomic-scale insight into well-defined
single crystalline, thin-film, and nanoscale surfaces exposed Pt dissolution trends that
governed the design and synthesis of durable materials. A newly defined metric, intrinsic
dissolution, is essential to understanding the correlation between the measured Pt loss,
surface structure, size and ratio of Pt-nanoparticles in carbon support. It was found that utilization of Au underlayer promotes ordering of Pt surface atoms towards (111)- structure, while Au on the surface selectively protects low-coordinated Pt sites. This
mitigation strategy was applied towards 3 nm Pt3Au/C nanoparticles, resulting in
elimination of Pt dissolution in liquid electrolyte, including 30-fold durability improvement
vs. 3 nm Pt/C over extended potential range up to 1.2 V.
