摘要： A catalyst for preparing a carbon nanocoil which comprises a carbide catalyst comprising the elements of (transition metal element, In, C) or (transition metal element, Sn, C), or comprises a metal catalyst comprising the elements of (Fe, Al, Sn) or (Fe, Cr, Sn). The transition metal element of the carbide catalyst is preferably Fe, Co or Ni. More preferable catalysts include Fe3InC0.5, Fe3InC0.5Snw and Fe3SnC. A catalyst comprising a porous carrier and the above catalyst carried thereon is capable of controlling the diameters of the wire and the coil of the resulting carbon nanocoil. The above catalyst allows the preparation of a carbon nanocoil with high efficiency, and it has been found through taking the catalyst nucleus attached on the apex of a carbon nanocoil as a true catalyst for preparing the carbon nanocoil and determining the structure of the catalyst nucleus.

摘要： A method for synthesizing carbon nanocoils with high efficiency, by determining the structure of carbon nuclei that have been attached to the ends of carbon nanocoils and thus specifying a true catalyst for synthesizing carbon nanocoils is implemented. The catalyst for synthesizing carbon nanocoils according to the present invention is a carbide catalyst that contains at least elements (a transition metal element, In, C) or (a transition metal element, Sn, C), and in particular, it is preferable for the transition metal element to be Fe, Co or Ni. In addition to this carbide catalyst, a metal catalyst of (Fe, Al, Sn) and (Fe, Cr, Sn) are effective. From among these, catalysts such as Fe 3 InC 0.5 , Fe 3 InC 0.5 Snw and Fe 3 SnC are particularly preferable. The wire diameter and the coil diameter can be controlled by using a catalyst where any of these catalysts is carried by a porous carrier.
