Purification of carbon nanotubes - ScienceDirect

2008-12-1 · Based on the above mechanism, Wang and coworkers developed a two-step purification using Sc-CO 2 as a solvent to clean metal impurities from as-grown SWCNTs produced by the HiPco process. The first step of this method is a pretreatment procedure using bulk electrolysis with ethylenediaminetetraacetic acid.
