Abstract
This paper describes the influence of a Fe-Co catalyst on growth of carbon
nanotubes (CNTs) by catalytic chemical vapour deposition of acetylene and
nitrogen gases. Ferrum-Cobalt supported with alumina or zeolite was used as
a catalyst. Comparison of the various types of the Fe-catalyst (Co, Al, and
Zeolite) leads to the conclusion that Co-catalyst is suitable for producing multi
wall carbon nanotubes (MWCNTs) and combination of Fe and Co provide a
good condition to the catalytic growth of CNTs. Prepared samples were
analysed by Raman spectroscopy (RS) and scanning electron microscopy
(SEM).
