【Abstract】 A simple and effective method for synthesis of multi-walled carbon nanotubes was presented.In this method,acetone was used as the carbon source and nickel nitrate as the catalyst precursor.Multi-walled carbon nanotubes had been obtained over copper plate by catalytic combustion technique.Acetone flame provided not only the carbon source necessary for the growth of multi-walled carbon nanotubes but also reaction conditions for the synthesis of multi-walled carbon nanotubes in this method.Then scanning electron microscopy,transmission electron microscopy and Raman spectroscopy were employed for characterization of sample.The results indicate that multi-walled carbon nanotubes were synthesized by acetone catalytic combustion technique,and the amount of disorder carbon for the sample was estimated by Raman characterization.The method has many advantages over other methods,such as simple setup,easy operation,less expensive cost,short preparation circle and the like.更多还原
