Abstract
A simplified and efficient method for preparing non-noble metal catalysts for oxygen reduction reaction (ORR) based on nitrogen containing metal organic framework (MOF) is provided. The method includes formation of a first MOF product through a mechano-chemical reaction between a first transition metal compound and a first organic ligand in the presence of a catalyst. It further includes formation of a second MOF product incorporating a second transition metal and a second organic ligand into the first-MOF product. The second MOF product is converted into an electrocatalyst via pyrolysis, and optionally post-treatment. The electrocatalysts are applicable in various electrochemical systems, including oxygen depolarized cathodes (ODC) for chlorine evolution.
