Double-walled carbon nanotubes (DWCNTs) have been synthesized by a floating catalytic chemical vapor deposition method (FC-CVD) in diameter-varied reactor with xylene as carbon sources, ferrocene as catalyst precursor, and sulfur as additive. The as-grown products were characterized by scanning electron microscope (SEM), transmission electron microscope (TEM), and Raman spectrometer. The results show that DWCNTs with a high graphite degree is centimeter-scale in length, and the inner diameter varies in the range of 1.5-1.7 nm. The effect of reactor diameter on the structure and morphology of the products was also investigated and compared. It is believed that the diameter-varied reactor may become a feasible route to the mass and continuous production of DWCNTs.
