Method and device for deposition by pyrolysis of carbon nanotubes or nanotube carbon doped with nitrogen.

摘要

Process for preparing carbon nanotubes or nanotube nitrogen-doped carbon, by pyrolysis in a reactor chamber of a liquid containing at least one liquid hydrocarbon precursor of carbon or at least one liquid compound precursor of carbon and nitrogen consisting of atoms carbon, nitrogen and where appropriate hydrogen atoms and / or other chemical elements such as oxygen, and, where appropriate, at least one metal compound precursor of a catalyst metal, in which said pressurized liquid gets in the form of finely divided, such as droplets, through a specific injection system, preferably paper, and finely divided particles such as droplets, thus formed, liquid particles are transported by a gas stream vector and introduced into the chamber reaction, where the deposition and growth of carbon nanotubes or nanotubes c are performed arbon doped with nitrogen.
