Nitrogen‐doped graphene/graphene‐tube nanocomposites are prepared by a hightemperature approach using a newly designed cage‐containing metal‐organic framework (MOF) to template nitrogen/carbon (dicyandiamide) and iron precursors. The resulting N‐Fe‐MOF catalysts universally exhibit high oxygen‐reduction activity in acidic, alkaline, and non‐aqueous electrolytes and superior cathode performance in Li‐O 2 batteries.
