Resumen
Carbon nanotubes with single and few walls are highly appreciated for their
technological applications, regardless of the limited availability due to their high
production cost. In this paper we present an alternative process that can lead to lowering
the manufacturing cost of CNTs of only few walls by means of the use of the spray
pyrolysis technique. For this purpose, ferrocene is utilized as a catalyst and aliphatic
alcohols (methanol, ethanol, propanol or butanol) as the carbon source. The
characterization of CNTs was performed by scanning electron microscopy (SEM) and
transmission electron microscopy (TEM). The study of the synthesized carbon nanotubes
(CNTs) show important differences in the number of layers that constitute the nanotubes,
the diameter length, the quantity and the quality as a function of the number of carbons
employed in the alcohol. The main interest of this study is to give the basis of an efficient
synthesis process to produce CNTs of few walls for applications where small diameter
is required.
