Abstract: Single-walled carbon nanotubes (SWNTs) were synthesized by a hydrogen arc discharge method. A high yield of gram quantity of SWNTs per hour was achieved. Tow kinds of SWNT products: web-like substance and thin films in large slices were obtained. Results of resonant Raman scattering measurements indicate that the SWNTs prepared have a wider diameter distribution and a larger mean diameter. Hydrogen uptake measurements of the two kinds of SWNT samples (both as prepared and pretreated) were carried out using a high pressure volumetric method, respectively. And a hydrogen storage capacity of 4 wt pct could be repeatedly achieved for the suitably pretreated SWNTs, which indicates that SWNTs may be a promising hydrogen storage material.
