NON-PRECIOUS METAL BASED WATER ELECTROLYSIS CATALYST FOR OXYGEN EVOLUTION AT ANODE AND HYDROGEN EVOLUTION AT CATHODE AND PREPARATION METHOD OF THE SAME

摘要

Disclosed is a non-precious metal based water electrolysis catalyst represented by CoX/C (X is at least one selected from the group consisting of P, O, B, S and N) for evolution of hydrogen and oxygen at a cathode and anode, respectively, at the same time, the catalyst including a cobalt-containing compound fixed to a carbon carrier.
