Figure 3. (A) ORR curves and (B) derived Tafel slopes Co_SA+NC/SC, Co_SA+NC/NSC and Co_SA+NC/NPSC; (C) Chronoamperometric response of Co_SA+NC/SC, Co_SA+NC/NSC and Co_SA+NC/NPSC catalyst at 0.7 V; (D) OER polarization curves; (E) overpotential and (F) the corresponding Tafel slopes of Co_SA+NC/SC, Co_SA+NC/NSC, and Co_SA+NC/NPSC catalysts; (G) The chronopotentiometry curves of Co_SA+NC/SC, Co_SA+NC/NSC, and Co_SA+NC/NPSC were taken at 10 mA cm^-2; (H) The potential gap (ΔE = E_j=10 - E_1/2) of different catalysts. ORR: Oxygen reduction reaction; OER: oxygen evolution reaction.
