摘要：

The adsorption of methane inside single-wall carbon nanohorns (SWNH) was analyzed. SWNH pellets were found to store methane 160 v/v at 3.5 MPa and 303 K. It was observed that the adsorption in the internal spaces of SWNH tubes is enhanced as the concentration of methane increases in the interstitial spaces. This suggests that the enhancement of methane adsorption inside SWNH tubes is brought about by the unique mutual-arrangement of SWNH tubes.
