- - MANUFACTURING METHOD OF GRAPHENE QUANTUM DOTS-PHTHALOCYANINE COMPLEX FOR ELECTROCHEMICAL CATALYST AND GRAPHENE QUANTUM DOTS-PHTHALOCYANINE COMPLEX USING THE SAME

摘要

The present invention relates to a graphene quantum dot-phthalocyanine composite for an electrochemical catalyst and a method for producing the same, wherein the graphene quantum dot-phthalocyanine composite is prepared by dispersing a graphene quantum dot in an organic solvent to prepare a graphene quantum dot solution, Adding phthalocyanine to the graphene quantum dot solution in which graphene quantum dots are dispersed to form a mixture, adding pyridine as a reaction catalyst to the mixture, and adding the reaction mixture to the mixture at a predetermined reaction temperature And stirring the mixture for a predetermined period of time to form a graphene quantum dot-phthalocyanine composite. The graphene quantum dot-phthalocyanine composite prepared by the above method can be applied as a catalyst for an oxygen reduction reaction (ORR) in place of a conventional platinum catalyst in which one or more phthalocyanine molecules are bonded to graphene quantum dots .
