Catalyst for synthesizing carbon nanocoils, synthesising method of the same and synthesizing method of carbon nanocoils

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.
