Product Code: CNB-8-TNMC2

TimestubTM --Purified Multi-walled carbon nanotubes---There are three kinds of products in this catalog: TNM2, TNMH2 and TNMC2. TNM2 is produced by acetylene catalytic decomposition over Ni-based catalyst.TNM2 often exists in bundles. TNMH2 and TNMC2 are TNM2 hydroxyl and carboxyl derivates, respectively. They are produced by KMnO4 oxidation in H2SO4 solution at different temperature and KMnO4 concentration.
