Movies S1 and S2

Movie s1 (O2 bubbles 1).
The same electrode as above starting with no applied potential and applying 1.29 V (vs. NHE).

Movie s2 (O2 bubbles 2).
The surface of the ITO anode at 1.29 V (vs. NHE) applied potential in 0.5 mM Co2+ in KPi electrolyte after 6h of in situ catalyst formation. The current density is 1 mA/cm2.
