Figure Legend:
(a) LSV profiles of a platinum RDE tip in 85% phosphoric acid solution at 90°C. At 2500 rpm, the electrode potential was cathodically swept at 10 mV/s after the Pt electrode was stabilized at open circuit potential, 0.8 V, (solid line) or at 0 V (dashed line). (b) CV curves of commercial platinum catalyst in 85% phosphoric acid solution at 90°C. The scan rate was 10 mV/s and the electrode rotation speed was 900, 2500, and 4900 rpm.
