Competitive adsorption of He-4 and H-2 on single-wall carbon nanotube bundles

摘要

We have used a temperature-programmed desorption technique to observe that H-2 binds preferentially vs. He-4 on closed-tube single-wall carbon nanotube bundles. Whether this H-2 preferential binding occurs in the interstitial channels or on the outer-grooves has not yet been unambiguously determined. (C) 2003 Elsevier Science B.V. All rights reserved.
