Methods for Purification of Carbon Nanotubes Obtained from Fullerene Production Deposits

摘要

Methods of preparation and purification of nanocarbon materials(nanotubes,nanobarrels,nano-bulbs)from deposits formed in fullerene production were developed.Since the beginning of extensive studies of carbon nanotubes(CNTs)and other nanostructures in 1991 [1,2],the separation of CNTs from concomitant products(amorphous carbon,graphite,and sometimes catalyst metal particles)has become an increasingly topical problem,strongly affecting the CNT cost.
