Preparation of Carbon Nanotubes Using Iron Oxide(III) Nanoparticles Size-Controlled by Phenylazomethine Dendrimers

Abstract

Dendritic polyphenylazomethine (DPAG4) can precisely incorporate any number of metals onto the imine sites. After spin casting of the solution of the complex between DPAG4 and iron trichloride(III) (FeCl3) on the substrate, iron oxide(III) nano dots could be prepared by hydrolysis of the complex fabricated on the substrate. The diameters and heights of the iron oxide could be controlled based on the molar amount of incorporated FeCl3 in DPAG4. Using these iron oxide nano dots as the catalyst, we attempted to fabricate carbon nanotubes on the bare silicon substrate by reacting with a mixed gas at high temperature.
