Methods and compositions for use in the preparation of MOF-based non-PGM electrocatalysts including combining transition metal compounds with organic ligands and secondary building units to create a solid mixture, heating the solid mixture to form a MOF through a solid-state reaction, optionally heating the MOF to convert it to an electrocatalyst via pyrolysis, and optionally post-treating. The electrode catalysts may be used in various electrochemical systems, including a proton exchange membrane fuel cell.

Synthesis of electrocatalysts using metal-organic framework materials

A method of preparing a nitrogen containing electrode catalyst by converting a high surface area metal-organic framework (MOF) material free of platinum group metals that includes a transition metal, an organic ligand, and an organic solvent via a high temperature thermal treatment to form catalytic active sites in the MOF. At least a portion of the contained organic solvent may be replaced with a nitrogen containing organic solvent or an organometallic compound or a transition metal salt to enhance catalytic performance. The electrode catalysts may be used in various electrochemical systems, including an alkaline fuel cell.
