NANOCARBON MATERIAL ENCAPSULATING METAL AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a nanocarbon tube material encapsulating a metal and a method for producing the same.

SOLUTION: A carbon nanomaterial is a material originated from fullerene nanofiber encapsulating a particle of a metal or of a metal-containing compound and is either among carbon nanotube, carbon nanocapsule and cup stack type carbon nanotube. The method for producing the carbon nanomaterial encapsulating a metal comprises: (A) a process for preparing a first solution by dissolving fullerene molecules in a first solvent; (B) a process for preparing a second solution by adding a metal-containing salt in a second solvent having lower dissolving ability of the fullerene molecule than that of the first solvent; (C) a process for forming a liquid-liquid interface between the first solution and the second solution by adding the second solution to the first solution; (D) a process for precipitating a fullerene fine wire encapsulating a metal in the solution; and (E) a process for obtaining the carbon nanomaterial encapsulating a metal by carrying out heat treatment of the fullerene fine wire encapsulating a metal at predetermined temperature.
