摘要

Using the Grand Canonical Monte Carlo simulation technique we study the storage of SF₆ on the bundles of single-walled carbon nanotubes. We show that nanotube bundles may be efficient SF₆ storage vessels, and there is no influence of chirality on adsorption. In the case of SF₆ adsorption from the mixtures containing low concentration of this gas, the smallest tubes are the most promising adsorbents. Also the bundles composed of tubes having diameters 2.7-2.8 nm and accessible intestinal porosity are efficient. These tubes are also optimal for the high pressure SF₆ volumetric storage.
