Abstract
The oxygen evolution reaction (OER)-catalyzing activity of transition metal perovskite oxide catalysts depends on the occupancy of the σ-bonding orbital of esymmetry parentage of the active cation. Catalysts having preferred values of eorbital filling can have a high intrinsic activity for catalysis of the OER.
