MANUFACTURING METHOD OF OXYGEN REDUCTION REACTION CATALYSTS AND CATALYSTS THEREOF, CATHODE USING OXYGEN REDUCTION REACTION CATALYSTS

摘要

This invention relates to a method of preparing an oxygen reduction reaction catalyst, an oxygen reduction reaction catalyst prepared thereby, and an electrode for a metal-air battery using the oxygen reduction reaction catalyst, wherein transition metal ions are adsorbed on a commercially available melamine foam and carbonized, and carbon black is supported on a porous structure of the carbonized melamine foam support, thereby economically preparing the oxygen reduction reaction catalyst that is able to maximize an effect of promoting the oxygen reduction reaction.
