Low Cost Synthesis of Single Walled Carbon Nanotubes from Coal Tar Using Arc Discharge Method

High-yield synthesis of single-walled carbon nanotubes by gravity-free arc discharge

Single-walled carbon nanotubes ~SWNTs! have been produced in high yield by the dc arc discharge technique under gravity-free conditions. Gravity-free conditions can reduce the convection flow of the buffer gas during the arc discharge, which results in the increase of high thermostatic volume around the arc flame. The yields of both the total soot and SWNTs in soot are significantly increased. ...

Dispersion and characterization of arc discharge single-walled carbon nanotubes--towards conducting transparent films.

This study addresses a combination of a well-developed and mild dispersion method and high-quality arc discharge single-walled carbon nanotubes (SWCNTs) as starting materials. Thus, we advance in fabrication of transparent, conducting films with extraordinary low material loss during SWCNT processing. The starting material was characterized by means of thermogravimetric analysis, high-resolutio...

Controlled Cvd Synthesis of Single-walled Carbon Nanotubes from Alcohol

By using alcohol as carbon source, high-purity single-walled carbon nanotubes (SWNTs) can be generated at relatively low CVD temperatures from metal catalysts supported with zeolite [1]. Based on these findings, we have proposed alcohol catalytic CVD (ACCVD) technique. In addition to the conventional metal particles supported on zeolite, we have developed a simple dip-coat method to directly di...
