Abstract

Abstract: Carbon nanoparticles produced from alcohols by pulsed spark discharge in liquid (PSDL) was investigated in this work. The spherical carbon particles with about 10 nm diameter can be produced by PSDL, which were similar to the commercial carbon particles. With the increase of discharge power, the mean diameter of carbon particles was decreased and the size distribution was more uniform. Meanwhile, the yield of carbon produced from ethanol was more than from methanol that may be attributed to the more carbon atoms in ethanol compared with the same volume of methanol. In addition, the mechanism of carbon produced from alcohols by PSDL was also analyzed. The possible reactions were given according to the production analysis. This work presents a new method for carbon nanoparticles production and the results can play a guidance role in producing nanometer materials by plasma reforming.
