Method for production of carbon nanotube and method for purification of the same |
摘要 |
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. |

1. A method for producing purified carbon nanotube comprising:
providing a carbonaceous material comprising carbon nanotube and not comprising iron; and purifying the carbon nanotube by adding an iron-containing material and hydrogen peroxide to the carbonaceous material to facilitate removal of impurities present in the carbonaceous material, wherein the iron-containing material is an iron-containing carbonaceous material obtained by striking an arc discharge between a pair of electrodes, wherein at least the positive electrode is an iron-containing carbon molding, and causing the deposition of evaporated material produced from the positive electrode. |
