Aerosol CVD technique was employed at atmospheric and low pressures and ferrocene was used as a catalyst. It is shown that at atmospheric pressures carbon nanotubes were formed only from a gasoline fraction. Lower pressure in the reactor during the synthesis process leads to formation of carbon tubular structure from both petroleum fractions-gasoline and jet fuel. Other modifications of carbon were grown at atmospheric pressure in a case used fraction jet fuel and diesel fraction. MWCNTs with diameters of 35 - 65 nm have been grown at lower pressure in the reactor using gasoline fraction. The diameter of the MWNTs grown at atmospheric pressure in the reactor was in the range of 80 - 215 nm and the length reached 6 microns after the purification process.展开更多
