  author={Chang Liu and Peng-Xiang Hou and Hui-Ming Cheng},
As-prepared carbon nanotubes (CNTs) usually contain impurities like amorphous carbon, graphitic carbon and residue catalyst. To evaluate the intrinsic property of CNTs and to realize their applications [1], it is necessary to have raw CNT samples purified. A principle for CNT purification is to thoroughly remove impurities while well keeping the CNT structure intact. To achieve this objective, quite a few purification techniques have been developed. In this presentation, various purification… CONTINUE READING
