Samtsov UDC 541.16 678.675(088.8) Results of experimental investigations of the conditions of formation of carbon nanomaterials in the decomposition of methane in the plasma of a high-voltage atmospheric-pressure discharge have been presented. The influence of the temperature gradient, the cathode material, and the deposition-surface material on the process of formation of carbon nanostructures has been investigated. It has been established that the processes of catalytic decomposition of methane occur, with a large degree of probability, on the metallic deposition surface in the presence of the temperature gradient between the gas flow and the surface.
