Abstract: 본 발명은 대량 생산에 적합하고 제조비용을 절감할 수 있는 연료전지용 합금 촉매를 제조하는 방법에 관한 것으로서, 2이상의 촉매 전구체를 별도의 기화기에서 기화시키는 단계; 기화된 2이상의 촉매 전구체를 서로 접촉시키지 않고 반응기에 공급하는 단계; 및 상기 반응기에서 합금 촉매를 합성하는 단계를 포함하여 구성된다.
본 발명의 연료전지용 합금촉매 제조방법은, 종래의 복잡한 다단계의 촉매 제조방법에 비하여 단일 반응공정으로 합금 촉매를 제조할 뿐만 아니라 종래의 합금 제조 공정에 비하여 현저히 낮은 온도에서 합금을 형성함으로써, 대량생산에 적합하며 공정비용을 절감할 수 있는 효과가 있다.
또한, 본 발명에 따라 제조된 합금 촉매 입자는 기존의 방법으로 제조된 촉매에 비하여 크기가 나노 단위로 현저하게 작기 때문에, 반응 활성점의 수가 크게 향상되어 나노화에 따른 촉매 원가를 절감할 수 있고, 금속 촉매와 지지체 간의 상호작용이 증가하여 내구성이 향상되는 등의 다양한 효과를 얻을 수 있다.

Abstract: The present invention relates to a production method of a metal-carbon composite having a core-shell structure in which nanometal particles forms cores and carbon forms shells in a powder form for a form in a carrier using co-vaporization, and the metal-carbon composite having the core-shell structure produced by the same. By the production method, the composite having the core-shell structure is capable of being synthesized by vaporizing organic precursors containing metal and carbon at the same time using co-vaporization, and a separate post-treatment process is unnecessary. The composite has high functionality and durability by not generating the corrosion, coagulation, or separation of metal particles when the composite is applied to a severe reaction process in high temperatures, acidic or alkali environment, or for a long time by covering the surface of the metal with carbon shells.
