CATALYST FOR PRODUCING CARBON NANOCOIL AND PROCESS FOR PRODUCING CARBON NANOCOIL USING THE CATALYST

摘要

Disclosed is a catalyst for producing a carbon nanocoil (CNC) by CVD that is inexpensive and can be stably supplied and particularly can exert a high level of catalyst activity even though the catalyst does not contain In as the catalyst component.  Also disclosed is a process for producing a carbon nanocoil using the catalyst.  The catalyst is used for the production of a carbon nanocoil by chemical vapor deposition using a carbon-containing pyrolysis gas and comprises (1) Fe, (2) Sn, and (3) an alkali metal and/or an alkaline earth metal.
