View the Complete Application at the US Patent & Trademark Office
The oxygen evolution reaction (OER)-catalyzing activity of transition metal perovskite oxide catalysts depends on the occupancy of the .sigma.-bonding orbital of e.sub.g symmetry parentage of the active cation. Catalysts having preferred values of e.sub.g orbital filling can have a high intrinsic activity for catalysis of the OER.
