Beschreibung
Zusammenfassung:	The present invention provides a preparation method of a metal-carbon composite which comprises: a step of providing a porous catalyst; a step of synthesizing a carbon material on a surface of the porous catalyst; a step of removing the porous catalyst to form a three-dimensional porous carbon structure; a step of placing and complexing a metal in the three-dimensional porous carbon structure to form a metal-carbon composite; and a step of compressing the metal-carbon composite to control the porosity of the metal-carbon composite. 본 발명은, 다공성 촉매를 제공하는 단계; 상기 다공성 촉매 표면에 탄소소재를 합성시키는 단계; 상기 다공성 촉매를 제거하여 3 차원 다공성 탄소 구조체를 형성하는 단계; 상기 3 차원 다공성 탄소 구조체 내부에 금속을 위치시키고 복합화하여 금속-탄소 복합체를 형성하는 단계; 및 상기 금속-탄소 복합체를 압착하여 상기 금속-탄소 복합체의 기공률을 조절하는 단계; 를 포함하는 금속-탄소 복합체의 제조방법을 제공한다.
