    • A method for manufacturing carbon nanocoils which are grown by winding carbon atoms in a helical configuration and which have an external diameter of 1000 nm or less, the method comprising the steps of: placing an indium-tin-iron type catalyst inside a reactor, heating an area around the catalyst to a temperature equal to or greater than temperature at which hydrocarbon used as a raw material is broken down by an action of the catalyst, causing hydrocarbon gas to flow through the reactor so that the gas contacts the catalyst, and allowing carbon nanocoils to grow on a surface of the catalyst while the hydrocarbon is broken down in the vicinity of the catalyst. The indium-tin-iron type catalyst may be obtained by: a mixed catalyst of indium oxide and tin oxide, and a thin film of iron which is formed on a surface of this mixed catalyst.
    • 一种制造碳纳米薄膜的方法,其通过将螺旋形状的碳原子缠绕并且具有1000nm或更小的外径而生长,所述方法包括以下步骤:将铟 - 锡 - 铁型催化剂置于反应器内,加热 催化剂周围的区域达到等于或大于用作原料的烃的温度的温度,通过催化剂的作用被分解,导致烃气体流过反应器,使得气体与催化剂接触,并允许 碳纳米薄膜在催化剂表面生长,同时烃在催化剂附近分解。 铟 - 锡 - 铁型催化剂可以通过以下方法获得:氧化铟和氧化锡的混合催化剂和形成在该混合催化剂的表面上的铁的薄膜。
