CARBON NANOSTRUCTURES GROWN ON Fe-Cr-Al ALLOY

Mária Čaplovičová – Ľubomír Čaplovič – Dalibor Búc – Peter Vinduška – Ján Janík

   The morphology and nanostructure of carbon nanotubes (CNTs), synthesized directly on Fe-Cr-Al-based alloy substrate using an alcohol catalytic chemical vapour deposition method (ACCVD), were examined by transmission electron microscopy (TEM). The grown CNTs were entangled with chain-like, bamboo-like, and necklace-like morphologies. The CNT morphology was affected by the elemental composition of catalysts and local instability of deposition process. Straight and bended CNTs with bamboo-like nanostructure grew mainly on $\gamma\text{-Fe}$ and $\text{Fe}_3\text{C}$ particles. The synthesis of “necklace-like” nanostructures was influenced by silicon oxide, and growth of chain-like nanostructures was supported by a catalysts consisting of Fe, Si, oxygen and trace of Cr. Most of nanotubes grew according to base growth mechanism.

Keywords: carbon nanotubes, alcohol catalytic chemical vapor deposition, transmission electron spectroscopy
