Carbon nanotubes produced from hexane and ethanol

Abstract

The synthesis of multi-wall carbon nanotubes using hexane or ethanol as the carbon source, hydrogen as the carrier gas, and iron as the catalyst with a thermal chemical vapor deposition method, is reported. It was found that the use of ethanol as the carbon source under low temperature (700$^{\circ}$C) gives better results than other liquid precursors in obtaining long and clean carbon nanotubes on quartz substrates.
