Experimental Analysis of the Long Carbon Nanotubes Formation from Controllable Flame

Flame method is a new and simple method which may has the possibility of large-scale mass production for the synthesis of carbon nanotubes. It needs not the vacuum environment and carbon nanotubes can be captured at the normal atmospheric pressure. Synthesis of carbon nanotubes from the controllable flame is a new method. It can effectively avoid the defect of the traditional flame method. Experimental apparatus is mainly including controllable flame burner with its ancillary equipment, measuring instrument and catalyst preparation system, etc. The process of formation and growth for carbon nanotube is very complicated on account of the complexity of combustion and chemical reaction. It can be supposed that the formation and growth of carbon nanotubes from the controllable flame involves two steps in general.
