Abstract

Multiwalled carbon nanotubes have been prepared using catalytic decomposition of solutions of ferrocene in liquid hydrocarbons: n-hexane, benzene and xylenes. The solutions were injected into the reaction furnace using Ar as carrier gas. The experimental investigations were effectuated in a home-made experimental setup using the spray-pyrolysis method, a liquid carbon source based variant of chemical vapor deposition (CVD). The reaction products were analyzed by TEM. The possible role of the hexagonal carbon-cluster based growth mechanism of carbon nanotubes is discussed..
