Nanocarbon materials formation in arc plasmatron

The article presents results of physico-chemical study of the deposit formed on the electrodes of an arc plasmatron when applying propane-butane mixture in the electrode gap. The studies were performed by means of optical, electronic, and Raman microscopy. According to Raman spectra various forms of nanocarbon were identified in the cathode deposit. Fact of synthesis of maleic anhydride and its covalent grafting to nanographite during operation plasmatron was found. It is shown that this construction arc plasmatron with supply of hydrocarbon gas can be considered as a mini-reactor for the synthesis of different forms of nanocarbon, the surface and physical-chemical properties modification.
