Manufacturing method of manganese oxide catalyst using multi wall carbon nano tube for zinc-air battery and manufacturing method of Cathode for zinc-air battery using thereof

摘要

PURPOSE: A manufacturing method of manganese oxide catalyst is provided to manufacture a manganese oxide catalyst at room temperature, to have simple production process, and to able t o control the amount of catalyst to be supported through simple concentration control. CONSTITUTION: A manufacturing method of manganese oxide catalyst comprises: a step of dispersing carbon nanotube into surfactant; a step of forming manganese oxide by dissolving manganese oxide precursor into a solvent; a step of dipping the manganese oxide into the carbon nanotube by mixing the solution manufactured by previous steps; a step of separating manganese catalyst powder from the solution through centrifugation; and a step of cleaning and drying the separated manganese oxide.
