Carbon nanostructures produced by chlorinating aluminium carbide

A number of carbon samples with different nanostructures such as: amorphous , nanoparticles and turbostratic, were synthesised through the reaction bet ween aluminium carbide and gaseous chlorine at fixed temperatures between 3 00 and 900 degreesC. The synthesised carbon samples were characterised usin g high-resolution transmission electron microscopy and X-ray powder diffrac tion techniques, as well as low temperature nitrogen sorption measurements. The carbon produced at T=300 degreesC was amorphous with a surface area of similar to 1400 m(2) g(-1). At 700 degreesC, a large amount of carbon nano particles and with a lower surface area similar to 710 m(2) g(-1) was obtai ned. At 900 degreesC, mainly a turbostratic carbon with a surface area of s imilar to 680 m(2) g(-1) was produced. (C) 2001 Elsevier Science Ltd. All r ights reserved.
