The possibility of the synthesis of carbon nanotubes by the method of chemical deposition of acetylene at 400-800 °C temperature on the surface of a metal film of amorphous alloy Ni-Ta-N with low nickel content (~ 25 at.%) has been demonstrated. It has been shown that an addition of nitrogen into the Ni-Ta alloy promotes the formation of tantalum nitride and extrusion on the surface of the nickel clusters, acting as a catalyst in the growth of carbon nanotubes. The Raman spectroscopy has revealed that while increasing the temperature of the synthesis process the quality of the carbon nanotubes is improved.
