Purified SWCNTs,-COOH functionalized
Product Code: CNB-8-TNSC
TimestubTM --Purified Single-walled carbon nanotubes---There are three kinds of products in this catalog: TNS, TNSH and TNSC. TNS is produced by methane decomposition over Co-based catalyst first, then experienced air oxidation to remove the amorphous carbon. TNSH and TNSC are TNS hydroxyl and carboxyl derivates, respectively. They are produced by KMnO4 oxidation in H2SO4 solution at different temperature and KMnO4 concentration.
