摘　　要：采用催化热解法制备了多壁纳米碳管,并对其进行酸化、灼烧、掺杂等一系列预处理后,在室温及氢气的压力分别为9,12MPa的条件下研究了多壁纳米碳管的储氢性能。通过对纳米碳管的不同处理可以提高纳米碳管储氢容量,掺杂金属锂后,纳米碳管的储氢量增加最大。Multi-wall nanotube was prepared with floating catalyst method. It was treated with heating, mixed acid or doped Li. They were stored hydrogen under p (H2)=12, 9 MPa at room temperature. Different treating methods affected hydrogen storage in multi-walled carbon nanotubes. The hydrogen storage capacity of carbon nanotube doped Li was the biggest.
