Abstract

Double-wall carbon nanotubes (DWCNTs) have been better prepared by thermally decomposing ferrocene mixed with sulphur in the mixture flows of argon and acetylene at 950-1150°C. The product of DWCNTs has been systematically studied as a function of the reaction temperature, the partial pressure of hydrocarbon, the sublimed temperature of ferrocene, and the relative molar value of ferrocene to sulphur. Our efforts to optimize the catalyst composition by replacing the partial ferrocene with cobaltocene have been proved to be inappropriate. In this process, the role of sulphur on the preparation condition has also been discussed.
