摘要：
Isosteric heat of adsorption and neutron diffraction measurements of hydrogen, methane, argon, oxygen and carbon dioxide adsorbed on single wall carbon nanotube bundles show that all adsorbates, except CO(2), condense first on high-energy binding sites like the grooves and the widest interstitial channels and then on the outer rounded surface of the bundles. As for CO(2), only one set of adsorption sites is observed, which is attributed to the grooves and/or the interstitial channels. (C) 2004 Elsevier B.V. All rights reserved.
