a ORR polarization curves (without iR correction, R  = 24.8 ± 0.4 Ω.) of L10-PtCoCr/C, L10-PtCo/C, and Pt/C in O2-saturated 0.1 M HClO4 (rotating speed, 1600 rpm; scan rate, 10 mV s−1). b ECSA and MA (@0.90 V vs. RHE) of the studied catalysts. c SA and SA retentions of the studied catalysts before and after ADT. d SA and SA retentions of L10-Pt-M-ETM catalysts. The potentials reported here are calibrated in RHE scale. The error bars are the s.d. from three separate measurements.
