Figure 3.

Effect of the temperature on the accelerated degradation tests (ADTs) performed at the potential window of 0.6–1.0 V_RHE (comparing RT and 75 °C, 5000 cycles, 1 V s^–1, 0.1 M HClO₄) comparing (a) ECSA_CO loss, (b) SA loss, and (c) Co loss of the ReCatalyst intermetallic dealloyed Pt–Co/C electrocatalyst. Comparison of the CO-electrooxidation CVs as well as the follow-up cycles before and after the ADT performed at (d) RT and at (e) 75 °C. Comparison of the ORR polarization curves before and after the ADT performed at (f) RT and at (g) 75 °C.
