Purified MWCNTs, -COOH functionalized (TNMC5)

Purified MWCNTs, -COOH functionalized (TNMC5)


Product Code: CNB-8-TNMC5

TimestubTM --Purified Multi-walled carbon nanotubes---There are three kinds of products in this catalog: TNM5, TNMH5 and TNMC5. TNM5 is produced by natural gas catalytic decomposition over Ni-based catalyst. TNMH5 and TNMC5 are TNM5 hydroxyl and carboxyl derivates, respectively. They are produced by KMnO4 oxidation in H2SO4 solution at different temperature and KMnO4 concentration.
