A brief review of catalytic vacuum synthesis of carbon nanoobjects on a dielectric substrate is presented. The authors argue that for the synthesis of carbon nanotubes during condensation from a vacuum arc discharge, it is advisable to use a copper layer as a catalyst on a dielectric substrate. The mechanism of synthesis of carbon nanotubes on a copper catalyst is described. The analysis of experimental data showed that the maximum yield of synthesized carbon nanotubes is achieved not on the solid copper layer, but on the island structure. The study is devoted to the study of modes of synthesis of the island structure of the copper catalyst and the identification of conditions for the synthesis of the island structure with a maximum perimeter of the Islands. It was found that the copper catalyst particularly contributes to the synthesis of single-layer carbon nanotubes. The level of undesirable impurities in the form of amorphous carbon and other types of carbon nanoobjects is quite low. In conclusion, recommendations on the optimal modes of synthesis of copper island catalyst on a dielectric substrate and methods of using atomic carbon on a copper catalyst from a vacuum arc discharge are proposed. |
