Adsorbate binding energy and adsorption capacity of xenon on carbon nanohorns

Description
Summary:Xenon adsorption studies were performed on aggregates of single-walled carbon nanohorns (SWNHs). The SWNHs were prepared in two different batches; the adsorption results from the two batches were essentially identical. Isotherms were performed in two groups of experiments: low-coverage data were used to measure the binding energy of Xe on the SWNHs, and full isotherms were measured to determine specific surface areas. The binding energy value for Xe on the SWNHs was intermediate between those for Xe on single-walled carbon nanotubes, and that for Xe on graphite. The specific surface area of the SWNHs was of the order of 250 sq m/g. (Author)
