a OER kinetic currents (normalised to the geometric surface area of the electrode, in mA cm−2geo) of SCO and Si–SCO collected in an O2-saturated 0.1 M KOH electrolyte under ambient conditions. The contribution from the conductive carbon as catalyst support is shown for reference. Inset shows the OER specific activity (normalised to the BET surface area of the oxide catalyst, in mA cm−2oxide) of SCO and Si–SCO at 1.60 V vs. RHE. Error bars are the standard deviations of triplicate measurements. b Steady-state Tafel data for SCO and Si–SCO.
