Effect of Organometallic Compounds on the Formation of Carbon Nanostructures by Pulsed Electric Discharge of Fluorine-Containing Organic Liquid between Metal Electrodes

Abstract

The carbon nanotube and carbon nanoparticle that contain fluorine on their surfaces were prepared by a pulsed electric discharge in a fluorine-containing organic liquid. The dominant product was nanoparticles with the diameters of ca. 5–100 nm in all experiments, however, the intensity ratio of G-band (1580 cm-1) to D-band (1350 cm-1) of the Raman spectrum of the products increased by addition of a catalyst indicating the formation of crystalline particles. The product formation rate also increased to 39.3 mg/A•s with ferrocene and 79.4 mg/A•s with nickelocene while with no catalyst it resulted in 12.5 mg/A•s.
