Carbon Nanotubes: Synthesis, Structure, Properties, …

Carbon nanotubes are fullerene-related structures which consist of graphene cylinders closed at either end withcontaining pentagonal rings. They were discovered in 1991 by the Japanese electron microscopist who was studying the material deposited on the cathode during the arc-evaporation synthesis of fullerenes. He found that the central core of the cathodic deposit contained a variety of closed graphitic structures including nanoparticles and nanotubes, of a type which had never previously been observed. A short time later, Thomas Ebbesen and Pulickel Ajayan, from Iijima's lab, showed how nanotubes could be produced in bulk quantities by varying the arc-evaporation conditions. This paved the way to an explosion of research into the physical and chemical properties of carbon nanotubes in laboratories all over the world.

Direct Synthesis of Carbon Nanotubes at Low …

The three main synthesis methods include arc discharge, laser vaporization, and chemical vapor deposition (CVD). The elements of carbon reaction chemistry in these three methods are in principle similar. However, in practice the processes are different by the degree of the initial excitation that starts the nanotube growth process, and the intermediate stages that the reactions go through during approaching the final state. A direct consequence of the high temperatures in arc discharge and laser vaporization that are required to evaporate solid carbon is the formation of a large variety of other carbon structures in the final product along with single wall CNTs (SWNTs). In addition, it was found that addition of a small amount (1%) of transition metal (Fe, Co, Ni) was necessary to obtain SWNTs.
