1. A method of preparing a high surface area electrode catalyst free of platinum group metals (PGM) for use in a fuel cell, comprising:

  • mixing a metal oxide, organic ligand, and transition metal complex;

    applying a first heat treatment sufficient to melt the organic ligand;

    reacting the organic ligand with the metal oxide to form a metal organic framework (“

    MOF”

    );

    interacting the transition metal with the MOF;

    applying a second heat treatment, converting organic components of the MOF to a carbonaceous material; and

    forming a catalytically active site by reacting the transition metal with nitrogen containing moieties.
