Pt x Fe/C/N-GC electrocatalysts were prepared using a composite of Hofmann-like Pt/Fe-based metal-organic frameworks and two-dimensional oxidized graphene. The Pt x Fe/C/N-GC-700 composite (annealed at 700 °C) exhibited an enhanced mass activity in the electrocatalytic methanol oxidation reaction, which was ten times higher than that of commercial Pt/C (20%) catalysts.
