Abstract

A simple method to fabricate carbon nanoparticles (CNPs) by passing an electric current through a carbon filament (CF) in liquid alcohol is reported. A large amount of gas bubbles (containing CO, H2, CO2, methane, ethane, acetylene and ethene) have been generated in the reaction between carbon and ethanol alcohol at a high temperature of about 2600 K. Scanning and transmission electron microscopy (TEM) images confirm the presence of carbon onion-like particles with diameters of about 20–50 nm. TEM images show that the spherical, disordered carbon onion-like particles seem to be in the majority. The carbon nanotubes are not formed under these conditions, which indicates that the nanoparticles are produced by thermal pyrolysis of alcohol vapors in the gas bubbles. Importantly, this carbonaceous production suggests that the carbon source in this method is mainly alcohol.
