Abstract

Long double-walled carbon nanotubes (DWNTs) could be synthesized in a production rate of about 0.5 g per h by an improved catalytic chemical vapor deposition method using xylene solution as carbon feedstock. The argon flowing rate affects the growth of DWNTs sensitively. Raman spectra and HRTEM images show that the DWNTs having inner diameters of about 1.0−2.0 nm dominate in the samples.
