Product Code: CNB-8-TNS

Timestub^TM --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.
