| Description | In present paper we describe a successful synthesis of carbon nanotubes (CNTs) in microwave plasma torch at atmospheric pressure from the mixture of methane, hydrogen and argon. The CNTs were grown on Si/SiO2/catalyst(Fe,Ni) substrates placed at various distances from the torch electrode either in direct contact with the torch or in remote plasma conditions.We have studied an effect of substrate position with respect to the torch electrode, methane-to-hydrogen flow rate ratio and substrate preparation. Optical emission spectra were taken along the discharge axis.The samples were imaged by scanning and transmission electron microscopes. Further information about the chemical structure was obtained from Raman spectroscopy. |
