Abstract
Carbon Nanotubes (CNTs) are usually synthesized by the chemical vapor deposition(CVD) of hydrocarbons over metal – inorganic oxide support systems. We have studied semi-quantitatively, the CVD of carbon from acetylene on (1) Fe2O3-MoO3 / MgO, (2) CoO-MoO3 / MgO, (3) Fe2O3-MoO3 / graphite and (4) Cs2O / MgO. We find that both the nature of the metal (Fe or Co) and the support (MgO or graphite) influence significantly, the yield of CNTs (vis-à-vis amorphous and graphitic carbon), and the nature of the CNTs formed. More CNTs were formed when Co rather than Fe was used. Also, MgO was a superior support compared to graphite.
