Carbon nanotubes growth from C2H2 and C2H4/NH3 by catalytic LCVD on supported iron-carbon nanocomposites
Artikel i vetenskaplig tidskrift, 2007

We report about the synthesis of carbon nanotubes by catalytic LCVD (C-LCVD), using a CW CO2 laser and alternatively, C2H2/ C2H4/NH3 and C2H2/C2H4-containing gas mixtures. Different core-shell Fe-C nanocomposites (as synthesized and toluene extracted) were used employed as catalysts. The nanotubes grown from Fe-C residue demonstrate the lowest mean diameters. Prevalent curled and coiled morphologies are obtained for the CNTs grown in the presence of ammonia. (c) 2006 Elsevier B.V. All rights reserved.
