摘要

用X射线吸收谱（XAS）和光电子能谱（PES）对化学气相沉积（CVD）方法制备的单壁碳纳米管纯化过程进行了研究。实验表明对碳纳米管进行盐酸处理纯化

可以大大减少残留在碳纳米管中的催化剂颗粒

但也发现盐酸中的部分氯离子与碳纳米管成键。这种成键作用可能会对碳纳米管形成修饰。

Abstract

A study on purification process of single wall carbon nanotubes(SWCNTs) synthesized by CVD method was performed using X-ray absorption spectroscopy (XAS) and photoelectron spectroscopy. Our experimental results showed that the purification process using hydrochloric acid was effective for the removal of metal particles. We also found the chemical bonding between some chlorine ions and the carbon nanotube and suggested that this bonding effect may lead to useful chemical modification of carbon nanotubes.
