Strategies to generate high-valence metal species capable of oxidizing water often employ composition and coordination tuning oxide-based catalysts, where strong covalent interactions with sites are crucial. However, it remains unexplored whether a relatively weak "non-bonding" interaction between ligands oxides can mediate the electronic states in oxides. Here we present an unusual non-covalent phenanthroline-CoO2 that substantially elevates population Co4+ for improved oxidation. We find...
