Experimental Comparative Study of Carbon Nanotubes Synthesized from CO and CH₄ by Flame Pyrolysis Method

Abstract:

In this paper, carbon nanotubes (CNTs) were synthesized by catalytic pyrolysis of CO and CH₄ using flame pyrolysis method. The effects of using the two different carbon sources to the preparation of CNTs with all other conditions being equal were comparatively studied. The results showed that: the morphology of CNTs synthesized from different carbon source gases had certain difference. Higher yield of carbon nanotubes could be synthesized using CH₄ as carbon source than using CO. At the same time, the former had less number of tube walls and the vascular bundles arranged more neatly. Synthetizing CNTs via catalytic decomposition of CH₄ had more advantages than using CO by flame pyrolysis method.
