A study of micropores in single-walled carbon nanotubes by the adsorption of gases and vapors

Abstract

Adsorption of N-2, benzene and methanol have been studied on as-prepared single-walled carbon nanotubes (SWNT) as well as SWNTs treated with HCl and HNO3. These nanotubes are good microporous materials with total surface areas well above 400 m(2)/g and internal surface areas of 300 m(2)/g or higher. Benzene molecules are shown to be adsorbed within the pores of the SWNTs. (C) 1999 Elsevier Science B.V, All rights reserved.
