        单壁纳米碳管是近年来材料科学以及凝聚态物理研究的前沿和热点。本研究提出一种有效制备单壁纳米碳管的半连续氢电弧法 ,实现了高纯度单壁纳米碳管的大量制备。在室温及中等压力下测定了氢电弧法制备单壁纳米碳管的储氢容量。初步研究结果表明 :单壁纳米碳管是一种很有前途的储氢材料

        Single walled carbon nanotube (SWNT) is a hot and frontier topic of materials science and condensed matter physics in recent years. A hydrogen arc discharge method for preparing SWNTs was developed in this research, by which high quality SWNTs can be synthesized in a large scale. The hydrogen storage capacities of the SWNTs synthesized by this method were investigated under moderate high pressure and room temperature, and the preliminary results showed that SWNTs are very promising for hydrogen storage.
