Abstract: front page image
(EN) 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.
(FR) La présente invention concerne un procédé de fabrication d'un nanocomposite à base de platine dans lequel est uniformément dispersé un catalyseur de platine, qui présente une large surface, et est stable et présente une activité catalytique élevée, un catalyseur à base de platine de pile à combustible ainsi fabriqué, et une pile à combustible l'utilisant, et concerne plus particulièrement un procédé de fabrication d'un nanocomposite de platine, de palladium et de point de carbone (Cdot), un catalyseur à base de platine de pile à combustible ainsi fabriqué, et une pile à combustible l'utilisant, le procédé comprenant les étapes consistant à : (A) faire réduire un précurseur de platine et un précurseur de palladium, dans un mélange de Cdot, du précurseur de platine et du précurseur de palladium de sorte à obtenir un nanocomposite sphérique nanodendritique dense ; et (B) graver de manière sélective le palladium dans le nanocomposite sphérique nanodendritique dense de sorte à conférer une porosité au nanocomposite.
(KO) 본 발명은 백금 촉매가 고르게 분산되어 있고, 표면적이 넓고, 안정하며, 촉매활성이 높은 백금계 나노복합체의 제조방법과 이에 따라 제조된 연료전지용 백금계 촉매 및 이를 이용하는 연료전지에 관한 것으로, 보다 상세하게는 (A) 카본닷(Cdot)과 백금 전구체 및 팔라듐 전구체가 혼합된 상태에서 백금 전구체 및 팔라듐 전구체를 환원하여 치밀한 나노수지상 구형 나노복합체를 제조하는 단계: 및 (B) 상기 치밀한 나노수지상 구형 나노복합체에서 팔라듐을 선택적으로 식각하여 다공성을 부여하는 단계:를 포함하여 제조되는 것을 특징으로 하는 백금, 팔라듐 및 Cdot의 나노복합체의 제조방법과 이에 따라 제조된 연료전지용 백금계 촉매 및 이를 이용하는 연료전지에 관한 것이다.
