摘要：

Single-wall carbon nanotube (SWCNT) bundles were pillared by fullerene (C-60) by the cosonication of C-60 and SWCNT in toluene to utilize the Interstitial pores for hydrogen storage. C-60-pillared SWCNTs were confirmed by the shift in the X-ray diffraction peak and the expanded hexagonal and distorted tetragonal bundles revealed by high-resolution transmission electron microscopy. The H-2 adsorptivity of the C-60-pillared SWCNT bundles was twice that of the original SWCNT bundles, indicating a design route for SWCNT hydrogen storage.
