Accelerated Surface Reconstruction in Double Perovskites: Enhancing Oxygen Evolution Reaction Activity Through Fe‐Doping
Fe‐doping is a well‐known strategy to enhance the oxygen evolution reaction (OER) activity of Ni‐based electrocatalysts, although the mechanism by which this occurs is widely debated. In this study, we use soft X‐ray absorption spectroscopy (sXAS) to demonstrate that Ni/Fe synergy in the double perovskite BaSrNi0.9Fe0....
