Non-platinum group metal electrocatalysts using metal organic framework materials and method of preparation

Patent Liu, Di-Jia; Ma, Shengqian; Goenaga, Gabriel A.

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 a proton exchange membrane fuel cell.
