We have demonstrated that the production of carbon nanotubes in large quantities is possible with inexpensive coal as the starting carbon source by the arc discharge technique. It has been found that a large amount of carbon nanotubes of good quality can be obtained in the cathode deposits in which carbon nanotubes are present in nest-like bundles. For the growth of carbon nanotubes, the buffer gas pressure in the reactor is one of the crucial factors. The mineral matter in raw coals may also play an important part in the formation process of carbon nanotubes.

摘要

The simulation studies of hydrogen adsorption in three types of ideal Y-junction carbon nanotubes (Y-CNTs) with open ends were carried out using molecular dynamics simulations and molecular mechanics calculations. The results show that the physisorption of hydrogen in Y-CNTs is very limited and far from the target set by DOE for hydrogen storage and transportation, implying that it is unlikely to achieve high hydrogen storage in open-ended Y-CNTs via physisorption scheme.
