Single-wall carbon nanotube (SWCNT) bundles were pillared by fullerene (C₆₀) by the cosonication of C₆₀ and SWCNT in toluene to utilize the interstitial pores for hydrogen storage. C₆₀-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 H₂ adsorptivity of the C₆₀-pillared SWCNT bundles was twice that of the original SWCNT bundles, indicating a design route for SWCNT hydrogen storage.
