To date,controversies remain in the unambiguous identification of active sites in N-doped carbons for oxygen reduction reaction(ORR).In the present study,prolonged potential cycling was conducted on three N-doped carbons in O2-saturated 0.1 M KOH aqueous solution,where apparent attenuation of the ORR activity was observed,within the context of limiting current and onset potential.
