methods for preparing doped carbon nanotubes with different elements

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.
