Abstract:
Molten Salt Electrochemical Preparation of Multi-walled Carbon NanotubesC. Schwandt, A.R. Kamali, A.T. Dimitrov, D.J. FrayDepartment of Materials Science and Metallurgy, University of Cambridge,Cambridge, CB2 3QZ, United KingdomGraphite may be converted directly into nano-structured carbonaceous material by way of electrolysis of molten alkali metal chlorides in the presence of graphite electrodes. However, because of the heterogeneous nature of the product and the low yields achieved to date, the method is generally regarded inappropriate for the production of carbon nanotubes.This presentation summarises recent research work that has the potential to change this view. By rigorously optimising the process parameters and implementing a novel type of process control, it has now become possible to prepare nano-structured carbonaceous material with nanotube contents as high as 70 to 80% in gramme quantities. The nanotubes are curved and multi-walled and occur in large agglomerates. The process is straightforward and uses conventional laboratory equipment, and thus has the potential to become a viable option for nanotube production.
