Stability and catalytic activity of metal oxides for the water oxidation at an electrolzyer anode are linked through the reactivity of oxygen atoms: metal–oxygen bonds are formed and broken during the electrocatalytic cycle, and metal–oxygen bonds are also what holds the material together. A way to probe this interplay is by isotope labelling of the oxygen in the electrocatalyst with 18O and determining by electrochemistry – mass spectrometry (EC-MS) whether this labelled oxygen is incorporated in the O2 released and/or unlabelled oxygen from the electrolyte is incorporated in the electrocatalyst during operation.
