The activation of small molecules was thought to be impossible on defect‐free wide‐band‐gap metal oxides owing to their chemical inertness. Based on microscopy and computational results, N. Nilius and co‐workers report in their Communication on page 11385 ff. that O 2 adsorption on CaO doped with Mo ions leads to the formation of superoxo species with a high propensity for dissociation. Activation takes place through charge transfer from the donor‐type Mo ions and proceeds even on ideal surfaces.
