A METHOD FOR REMOVING IMPURITIES FROM NANOSTRUCTURED CARBON MATERIAL AND PURIFIED NANOSTRUCTURED CARBON MATERIAL

摘要

Method for removing metal-containing impurities from a nanostructured carbon material comprises treating nanostructured carbon material in a thermal plasma of a process gas and subsequently separating from the process gas. An independent claim is also included for nanostructured carbon material manufactured according to the above method.
