Purification of single-wall carbon nanotubes by using ultrafine gold particles

Mizoguti E, Nihey F, Yudasaka M, Iijima S, Ichihashi T, Nakamura K

Ultrafine gold particles with a diameter of 20 nm were dispersed in carbonaceous soot containing single-wall carbon nanotubes (SWNTs). These gold particles catalyzed the oxidation of carbonaceous impurities at about 350 degrees C. This selective oxidation enabled us to purify SWNTs.
