(a) Oxygen reduction polarization curves of the carbon-based catalysts at rotation speed of 1600 rpm. The performance of the catalysts is compared to Pt/C and Vulcan XC-72 carbon black. Oxygen reduction polarization curves of the carbon-based catalysts in different rotation speeds and their corresponding Koutecky-Levich plots: (b) C-Pistachio, (c) C-Peanut, (d) FeCo/N-C-Pistachio, and (e) FeCo/N-C-Peanut. (f) Cyclic voltammogram of FeCo/N-C-Pistachio and FeCo/N-C-Peanut catalysts at a scan rate of 100 mV s-1.
