中文摘要：

本文采用YNi2合金为催化剂使用电弧放电的方法制备单壁碳纳米管。采用硝酸回流法进行处理，分别经过超声、回流、水洗、研磨、培烧，得到较纯净的碳纳米管。分别用近红外光谱、拉曼光谱、热重分析进行表征。纯化后的碳纳米管可以进一步用来化学修饰、金属和半导体性的分离等。

英文摘要：

Single -wall carbon nanotubes were produced by the arc discharge method with YNi2 alloy as a catalyst. Using nitric acid reflux, after each ultrasound , reflux grinding, calcine, and high - purity single - walled carbon nanotubes were obtained. Respectively, near, infrared, Spectroscopy, Raman TGA characte. The high - puritied single - wall carbon nanotubes can be used to further chemical modification and metals and semiconductors of separation.
