Abstract

Adsorption and storage of oxygen and nitrogen with 240º carbon Nanocone were studied and results were compared with (10,10) carbon nanotube. Adsorption amount of gases at constant temperature and different pressures was calculated by using the molecular dynamics method. The simulation results indicated that gases were adsorbed on external and internal surfaces of carbon Nanocone and carbon nanotube. Adsorption amount was increased and finally saturated by increasing pressure. It was found that oxygen adsorption was higher than nitrogen adsorption on both structures. Also, carbon Nanocones showed higher adsorption and separation capacity than carbon nanotubes. Therefore, carbon nanocones are a proper candidate for storage and separation of oxygen of the air.
