This led us to assume that other hydrocarbons, such as chlorinated hydrocarbons, could be used to make CNTs over this catalyst.

Carbon can, in principle, be removed by oxidation. I worked with the team at Growthink to accelerate the development of the original Integreon business plan. During synthesis, CNx material is uents for carbon could also modify the adsorption strength generated and deposited on the metal catalyst particle of the nanotube towards foreign elements quite signifi- where they react exothermically.

This catalyst was completely characterized as reported in our previous article. Some surface functionalization of carbon with chlorine is suggested when TTCE was used as reagent. It appears that all the aromatic chlorine containing reactants gave similar carbon yields ca. It was also revealed that the diameters of the tubes can carbon source and catalyst source, respectively. A limitation related to the use of CNTs in many applications has always been the difficulty in dispersing them in solvents.

Coville, Catalyst restructuring studies: Modification of the carbon surface and electronic properties has also been explored but the effect of chlorine Cl on the morphology of carbon nanomaterials is not well established.

Introduction Nanotechnology is a topic that is attracting the interest of scientists in academia, research institutions and industry as well as government officials and journalists.
