Effects of argon flow rate and reaction temperature on synthesizing single-walled carbon nanotubes from ethanol

The effects of argon (Ar) flow rate and the reaction temperature on synthesizing single-walled carbon nanotubes (SWCNTs) by means of the catalytic chemical vapor deposition (CCVD) method from ethanol over Fe–Mo/MgO catalyst have been investigated. The fluidized-bed was applied as the reactor. Ethanol vapor was introduced into the fluidized-bed from a temperature-controlled bubbler by the flow of carrier gas (Ar). The as-grown SWCNTs were characterized using Raman spectroscopic and transmission electron microscopy (TEM). The SWCNTs sample, which was synthesized by this equipment at 950 °C with the Ar flow rate 150 sccm, exhibited high quality.
