We have synthesized a large-scale synthesis of single-walled carbon nanotubes (SWNTs) by catalytic decomposition of ethylene over Fe-Mo / MgO catalyst at 700 oC. The produced carbon materials indicate the SWNT bundles with the diameter ranging from 11 -29 nm. The produced SWNTs which have the diameter of 0.7 – 2.8 nm, reveal no amorphous carbon deposit on the surface according to HRTEM observation and Raman analysis. The yield of nanotubes is over 550 wt%, which is obtained relative to the weight of Fe-Mo metal in Fe-Mo / MgO catalyst. Besides ethylene, we will discuss the large-scale synthesis of SWNTs according to different carbon containing sources such as acetylene and xylene.
