a Polarization curves for CR-Co/ClNC and references under 0.1 M O2-saturated KOH, 1600 rpm, scan rate of 10 mV s−1. b The contrast between CR-Co/ClNC and references for Jk and E1/2. The error bars are the standard deviations of three replicate calculation. c Tafel slopes and d Mass activity (MA) and turnover frequency (TOF) for CR-Co/ClNC and reference samples. The error bars error bars are the standard deviations of three replicate calculation. e Electron transfer number (top) and H2O2 yield (bottom) vs potential of CR-Co/ClNC and Pt/C. f Current-time chronoamperometric responses of CR-Co/ClNC and Pt/C.
