M. Nath et al., Production of bundles of aligned carbon and carbon-nitrogen nanotubes by the pyrolysis of precursors on silica-supported iron and cobalt catalysts, CHEM P LETT, 322(5), 2000, pp. 333-340
Pyrolysis of acetylene over iron or cobalt nanoparticles well dispersed on
silica substrates gives copious yields of aligned carbon nanotube bundles.
By carrying out the pyrolysis of pyridine over these catalyst surfaces, goo
d quantities of aligned carbon-nitrogen nanotube bundles have been produced
. The composition of the carbon-nitrogen nanotubes varies between C10N and
C33N, depending on the catalyst. (C) 2000 Elsevier Science B.V. All rights
