  • Method for production of carbon nanotube and method for purification of the same
    Patent number: 9067793
    Abstract: The present invention provides a method for producing a carbon nanotube having a high purity and a method for purifying an unpurified carbon nanotube or a carbon nanotube having a low purity. The method for producing a carbon nanotube comprises a step of providing a carbonaceous material containing a carbon nanotube and a step of adding an iron material and hydrogen peroxide to the carbonaceous material to thereby purity a carbon nanotube. It is preferred that an iron powder is used as the iron material. The iron powder is preferably used in a proportion of 0.5 to 20 parts by mass relative to 100 parts by mass of the whole carbonaceous material.
    Type: Grant
    Filed: September 6, 2011
    Date of Patent: June 30, 2015
    Assignee: Meijo University
    Inventors: Yoshinori Ando, Xinluo Zhao, Sakae Inoue
