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.
