a–f, fs-ECTAS of IrO2 under OCP (a) and 1.1 V (b), 1.3 V (c), 1.5 V (d), 1.7 V (e) and 1.9 V (f) potentials in 0.5 M H2SO4. Arrows indicate the characteristic signal peaks assigned to IrO2, Ir6+ and H+species, respectively. Milli-optical density (mOD) denotes the magnitude of the differential absorbance intensity.
