MANUFACTURING METHOD FOR CARBON DOT-PLATINUM-PALLADIUM COMPOSITE, CARBON DOT-PLATINUM-PALLADIUM CATALYST MANUFACTURED THEREBY, AND FUEL CELL USING SAME

摘要

The present invention relates to a manufacturing method for a platinum-based nanocomposite which has a platinum catalyst uniformly dispersed therein, has a wide surface area, and is stable and has high catalyst activity, a fuel cell platinum-based catalyst manufactured thereby, and a fuel cell using the same and, more specifically, to a manufacturing method for a nanocomposite of platinum, palladium, and carbon dot (Cdot), a fuel cell platinum-based catalyst manufactured thereby, and a fuel cell using the same, the method comprising the steps of: (A) reducing a platinum precursor and a palladium precursor, in a mixture of Cdot, the platinum precursor, and the palladium precursor to afford a dense nanodendritic spherical nanocomposite; and (B) selectively etching palladium in the dense nanodendritic spherical nanocomposite to impart porosity to the nanocomposite.
