A PROCESS OF PREPARING ELECTROCATALYSTS FOR OXYGEN REDUCTION REACTION BY USING STABILIZERS

摘要

PURPOSE: A manufacturing method of an electrocatalyst is provided to have a narrow particle size distribution, a small alloy particle size, a high carrier dispersion amount and uniformity, and low agglomeration due to temperature. CONSTITUTION: A manufacturing method of an electrocatalyst comprises a step of obtaining a carbon solution; a step of obtaining a precursor solution; a step of obtaining a mixed solution by mixing the carbon solution and the precursor solution; a step of preparing a stabilizer solution; a step of obtaining a stabilizer mixed solution by adding the stabilizer solution into the mixed solution; a step of manufacturing a reductant solution; a step of conduct the reaction between the stabilizer mixed solution and the reductant solution; a step of manufacturing a catalyst by removing suspended materials and washing and drying residues; and a step of treating the catalyst with heat.
