CATALYST FOR OXYGEN REDUCTION ELECTRODE AND PREPARING METHOD THEREOF |
摘要 |
PURPOSE: A manufacturing method of a catalyst for oxygen reduction electrode is provided to provide the catalyst for oxygen reduction with excellent oxygen reduction catalytic activity and electric conductivity through a simple production process supporting nanoparticles of metal or metal oxide onto a catalyst support. CONSTITUTION: A manufacturing method of a catalyst for oxygen reduction electrode comprises: a support of a graphene oxide nanosheet which is reduced after being modified by ionic liquid; and a nanoparticle of metal or metal oxide supported by the support. A manufacturing method of the catalyst for oxygen reduction electrode comprises: a step of manufacturing an oxidation graphene nanosheet modified by ionic liquid by reacting the oxidation graphene nanosheet with the ionic liquid; a step of manufacturing a support by reducing the oxidation graphene nanosheet; and a step of mixing the support with a precursor of the metal or metal oxide, and growing the metal and metal oxide on the support by a solution-based growth mechanism.
