| 摘 要： | 研究了经不同预处理后多壁碳纳米管的储氢性能.结果表明:多壁碳纳米管的吸附量在0～12 MPa范围内有一个极大值,极值点的压力和吸附量与样品的种类,处理方法等密切相关;不同量不同碱金属的掺杂对多壁碳纳米管吸附的影响稍有不同;加热活化对提高多壁碳纳米管的吸附量很有效,常温下,在将近9 MPa的平衡压力下,可以达到4.48%... |

| Abstract: | In this paper,the hydrogen storage in pretreated carbon nanotubes is studied.The results indicate that there exists an uptake maximum at certain pressure between 0~12 MPa,and this maximum is related with the kind and the treatment of the samples.For different quantity and different kinds of alkali-doped samples,the alkalis plays different roles.High-temperature activation is effective for adsorption.At room temperature,under 9 MPa,the highest uptake is about 4.48%（mass ratio）.Increasing ambient temperature properly benifits adsorption. |
