Abstract: N-S-Fe co-doped hierarchical porous carbon material was prepared by MgO/ZnCl₂ double template synergy and one-step pyrolysis, and the electrocatalytic performance of oxygen reduction reaction of the material was studied. The results show that the N-S-Fe co-doped hierarchical porous carbon material with carbon nanosheet structure was successfully synthesized, and had large specific surface area of 1140.31 m²·g^-1. The ZnCl₂ template could be conducive to the formation of micropores and dense active sites. The MgO template promoted the formation of mesopore, which could be beneficial to the mass transfer during electrocatalytic process of oxygen reduction reaction. The material exhibited excellent oxygen reduction electrocatalytic activity, good electrocatalytic stability and persistence, and high electron transfer rates in alkaline electrolytes. The onset potential, half-wave potential and charge transfer resistance were 1.05 V, 0.81 V and 11 Ω·cm², respectively. After 13h of polarization, 83% of the original current density was retained. The zinc-air battery assembled with the material had open circuit potential of 1.42 V and maximum power density of 182.1 mW·cm^-2.
