The Effect of Mechanochemical Treatment of the Catalyst in the Preparation of Carbon Nanotubes and their Electrical Properties

ABSTRACT

We report the mechanochemical effect of an Fe(NO$_3$)$_3$$.$9H$_2$O-Al(OH)$_3$sample as catalytic precursor mixed-ground by mixer mill on the growth of carbon nanotubes using thermal chemical vapor deposition method. From and TEM observations, carbon products grown on a ground catalyst were more uniform than those grown on an unground catalyst and most of them were identified as carbon nanobubes. Also, it was observed that field emission properties of products on ground catalyst were superior to those of unground catalyst.

Key words: Mechanochemical effect, Carbon nanotubes, Chemical vapor deposition
