a HOR polarization curves recorded in H2-saturated 0.1 M KOH with a sweeping rate of 50 mV s−1 at a rotation rate of 1600 rpm. b Representative HOR Tafel plots of kinetic current density. c ECSAs of i-M-PR/C at 50 mV (vs. RHE). d ECSA normalized specific activity and mass activity at 50 mV (vs. RHE). e Current retention rate of various catalysts in H2-saturated 0.1 M KOH solution at 100 mV (vs. RHE). f CO tolerance of i-M-PR/C evaluated at 100 mV (vs. RHE). g Scheme of the significance of oxophilic metal atoms on HOR performance. The error bars in (c, d) were obtained by three parallel experiments.
