Thermal and Electronic Excitation of Molecules Inside of Single Walled Nanotubes

摘要

The adsorption of gases inside single walled nanotubes (SWNTs) could supply a unique method for the removal of toxic wastes and chemical warfare agents from air streams. We have investigated the sorptive properties of SWNTs using infrared spectroscopy and other surface spectroscopic methods. It is found that the deep adsorption potential well associated with the interior of SWNTs supplies strong adsorption sites which are occupied initially by molecules encountering the sorbent. Four molecules have been studied: CF4, CCl4, NO and CO2.
