| 摘 要： | 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 substancea 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 SWMNTs,whicb indicates that SWNTs may be a promising hydrogen storge material.

| 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. |
