Growth of Carbon Nanotubes by Evaporating Ethanol as Carbon Source
We report the synthesis of carbon nanotubes (CNTs) from ethanol by a chemical vapor deposition (CVD) method. Ethanol used as carbon source is atomized by an ultrasonic evaporator at room temperature, and is injected into a CVD furnace through a nozzle installed inside the furnace. The SEM and TEM analysis shows that the product contained CNTs as major constituents with some impurities. The radial breathing mode (RBM) of Raman spectrum reveals that the SWNTs are included in the product. The average diameter of the MWNTs is about 30nm and that of the SWNTs is less than 2nm.
