Publication number: 20150056536Abstract: 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.Type: ApplicationFiled: September 8, 2014Publication date: February 26, 2015Applicant: UCHICAGO ARGONNE, LLCInventors: Di-Jia Liu, Shengqian Ma, Gabriel A.
