A novel core-shell-structured hybrid as an oxygen reduction reaction catalyst, consisting of nitrogen-doped porous Fe/Fe3C@C nanoboxes supported on graphene sheets, is synthesized through simple pyrolysis of graphene oxide-supported iron-based metal−organic frameworks. The hybrid exhibits higher electrocatalytic activity than a commercial Pt/C catalyst, excellent long-term stability, and superior methanol tolerance due to the synergistic effect between N-doped Fe/Fe3C@C and N-doped graphene sheets.
