In this report, we present a novel purification method of single-walled nanotubes (SWNTs) including their hydrothermal treatment by hydrothermally initiated dynamic extraction (HIDE) process. The purity of the SWNTs increases at each step of the integrated purification process (HIDE-extraction of fullerenes-oxidation-dissolution of metal particles) and the purity of the final product is over 95 wt.%. Furthermore, in order to study the detailed characterization of SWNTs, Resonant Raman scattering measurements were performed for the purified SWNTs.
