  text: Alkaline oxygen evolution on Co3O4 involves more than adsorption and electron
    transfer at a fixed surface. The article draws on operando electrochemical quartz
    crystal microbalance with dissipation monitoring (EQCM-D), surface X-ray diffraction
    (SXRD), Raman, UV/Vis and impedance spectroscopy. On this basis, it discusses
    pseudocapacitive oxidation of cobalt ion sites, electrolyte uptake and near-surface
    transformation, and asks which of these changes are kinetically coupled to electrocatalysis.
