The invention relates to a method, with the carbon-based nanoparticles made of graphitic carbon or modified by the incorporation of nitrogen and nanotubes from graphitic carbon nanotubes can be deposited on substrates and purposefully made. The present invention is based on the task to reason, a process to develop, carbon nano-materials and carbon nanotubes, and with the carbon nanotubes can be produced without high automated and temporal expense carbon nano-materials and nitrogen-containing. The technical problem is solved thereby that solid, pass undisintegrated vaporizable organic salts or not. Compounds with Transitional or. rare ground connection metals with a heating rate of 500 to 2000 K/minute and with substantial exclusion of oxygen be pyrolyzed.
