In order to address the issues of low durability, slow kinetics of the oxygen reduction reaction(ORR), and high cost of cathode catalysts for microbial fuel cells(MFC), a porous carbon co-doped with Fe, Zn, and N as an air cathode catalyst was prepared. The electrochemical studies demonstrated that the synthesised catalyst Fe/Zn-NC-0.9 exhibited excellent electrocatalytic activity for the oxygen reduction reaction. The charge transfer resistance and the exchange current density were measured at 5.6 Ω and 53.3 mV/dec, respectively, while the maximum power density was at(1 253±20)mW/m2. Additionally, the impact of the Fe doping level on the ORR reaction and maximum power density was assessed. It was found that a moderate Fe doping level is essential for enhancing catalytic activity. Furthermore, the cathode performance is improved through the synergistic effect of Fe and N co-doping.
