H-2 Adsorption Storage Capabilities of SWNTs and SWNTs-THF Hydrate

doi:10.3969/j.issn.0251-0790.2012.03.028

Abstract

Abstract:

Hydrogen absorption capability of three types of samples(dry SWNTs before and after concentrated acid treatment, and THF solution absorbed SWNTs) were compared. The results indicate that when temperature is 0.5 ℃ and pressure is 16.5 MPa, the hydrogen gas absorption rate of dry SWNTs before and after concentrated acid treatment are 0.75% and 1.15%(mass fraction), respectively. Hydrogen absorption rate of THF solution absorbed SWNTs is about 0.37%(mass fraction), lower than that of dry SWNTs because of the formation of THF hydrate.

Key words: Signal-walled carbon nanotubes(SWNTs), Hydrate, Hydrogen storage, Adsorption
