Product Description:          
Timestub^TM --Double-walled carbon nanotubes---There are three kinds of product in this catalog. They are TND, TNDH and TNDC.
TND was produced by methane catalytic decomposition over Co-based catalyst, followed treated by air oxidation and acid solution. TNDH and TNDC are TND hydroxyl and carboxyl functionalized products, respectively. This kind of product contains double-walled carbon nanotubes, single-walled carbon nanotubes, multi-walled carbon nanotubes and some amorphous carbon. The double-walled carbon nanotubes content is about 60wt%。
