Spinel oxides have attracted interest as water oxidation catalysts due to their efficiency and cost-effectiveness. Now, the covalency competition between tetrahedral and octahedral sites is shown to dominate the OER activity on spinel oxides, and the design principle is used to predict and confirm the superior activity of [Mn]T[Al0.5Mn1.5]OO4.
