Disclosed are: a metal nanostructure having a diameter of 2-2.5 nm; and a manufacturing method therefor. The formed metal nanostructure is provided as approximately spherical single-crystalline nanoparticles or amorphous alloy nanoparticles. Besides, a nanostructure fabricated in the form of an oxide has a nanoneedle shape. For formation of the metal nanostructure, an amorphous nanostructure is used. A second metal element having a higher standard reduction potential than a central metal constituting the amorphous nanostructure is used in the synthesis of the metal nanostructure. L'invention concerne : une nanostructure métallique présentant un diamètre de 2-2,5 nm ; un et procédé de fabrication associé. La nanostructure métallique formée est obtenue sous la forme de nanoparticules monocristallines ou de nanoparticules d'alliage amorphe, approximativement sphériques. En outre, une nanostructure fabriquée sous la forme d'un oxyde présente une forme de nano-aiguilles. Pour la formation de la nanostructure métallique, une nanostructure amorphe est utilisée. Un deuxième élément métallique présentant un potentiel de réduction standard supérieur à celui d'un métal central constituant la nanostructure amorphe est utilisé dans la synthèse de la nanostructure métallique. 2nm 내지 2.5nm의 직경을 가지는 금속 나노구조체 및 이의 제조방법이 개시된다. 형성된 금속 나노구조체는 대략 구형의 단결정 나노입자 또는 비정질 상의 합금 나노입자로 제공된다. 이외 산화물 형태로 제작되는 나노구조체는 나노 니들의 형상을 가진다. 금속 나노구조체의 형성을 위해 비정질 나노구조체가 이용된다. 비정질 나노구조체를 구성하는 중심 금속보다 높은 표준환원전위를 가지는 제2 금속 원소가 금속 나노구조체의 합성에 이용된다.
