▎ 摘　　要

NOVELTY - Carbon quantum dots-carbon support hybrid structure comprises carbon quantum dots; and a carbon support hybridly bonded to the carbon quantum dot. USE - Carbon quantum dots-carbon support hybrid structure used for catalyst for fuel cell (claimed). ADVANTAGE - The carbon quantum dot-carbon support hybrid structure has strong resistance to alcohol and anion adsorption, and has excellent electrocatalytic activity applicable to commercialization. The carbon quantum dot-carbon support hybrid structure can be applied as a catalyst for a fuel cell because structural stability and reproducibility are guaranteed, and has excellent price competitiveness compared to conventional catalysts even in mass production. The carbon quantum dot-carbon support hybrid structure manufacturing method has short synthesis time and enables mass production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for obtaining a carbon quantum dot-carbon support hybrid structure which involves (1) mixing hydrogen peroxide and a carbon precursor to produce a mixed solution; (2) dialysis after heating the mixed solution; (3) decompressing the mixed solution and vacuum drying to obtain carbon quantum dots; (4) hybridizing the carbon quantum dots and the carbon support; (5) synthesizing a carbon quantum dot-carbon support hybrid structure by cooling the combined carbon quantum dots and carbon support; and (6) depressurizing the carbon quantum dot-carbon support hybrid structure and vacuum drying.
