A one‐step synthetic strategy was employed to fabricate Fe 3 O 4 embedded in Fe 3 C nanoparticles encased in nitrogen‐doped carbon shells as effective ORR catalysts. The high ORR activity of Fe 3 O 4 /Fe 3 C@NC catalysts were found to be attributed to the synergetic effect between Fe 3 C nanoparticles wrapped in carbon shells, which improved the activity of ORR, and Fe 3 O 4 nanoparticles neighboring Fe‐N x that significantly increased the active sites of the catalysts.
