The hydrogen storage capacity of bamboo-shaped multiwalled carbon nanotubes (BS-MWNTs) in ambient conditions was studied by means of the volumetric method, and compared with those of single-walled carbon nanotubes (SWNTs) and multiwalled carbon nanotubes (MWNTs). The BS-MWNTs, whose herringbonelike structure was characterized by the transmission electron microscopy, showed the greatest hydrogen storage capacity with about 0.4 wt % at atmospheric pressure. The SWNTs showed a comparable hydrogen storage capacity, whereas the MWNTs were insensitive to the pressure change. Our work indicates that the herringbone carbon nanotube structure is more capable of hydrogen storage than the herringbone graphite nanofiber structure.
