Method for the synthesis and doping of carbon nanotubes Preparation comprising a support of Sol - gel containing an oxide of a transition metal Catalyst, the cultivation of the carbon nanotube, doping with a dopant Element nanotubes and nanotube purification; and Carbon doped

摘要

The present invention relates to a method for the synthesis and in-situ doping of carbon nanotubes (CNT). The method of the invention enables the manufacture of nanotubes in an economically viable way and free from amorphous carbon, resulting in that their purification is performed only by the catalyst, which process requires just a few washes with low-concentration commercial acid. Also, this process allows the in-situ doping of carbon nanotubes with different doping elements during and after growth.
