Fe–N–C exhibits excellent electrocatalytic oxygen reduction reaction (ORR) activity, but the synergistic effect between metallic and isolated iron species remains unclear. Herein, N-doped carbon nanostructure encapsulated Fe3C nanoparticles coupled with atomically dispersed Fe–N4 (Fe3C–FeN/NC) were...
