Research Abstract

Carbon nanotube was successfully grown on the substrate by using pre-synthesized Fe3O4 nanoparticles that were adsorbed in the monolayer fashion as for catalysts. Chirality of carbon nanotubes which are grown from the catalytic nanoparticles with narrow size distribution can be controlled. As for the next challenge to overcome the problems, improvement of catalytic ability should be referred. UV ozone treatment may help to reduce the impurity.
