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 between aluminium carbide and gaseous chlorine at fixed temperatures between 300 and 900 degreesC. The synthesised carbon samples were characterised using high-resolution transmission electron microscopy and X-ray powder diffraction 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 nanoparticles and with a lower surface area similar to 710 m(2) g(-1) was obtained. At 900 degreesC, mainly a turbostratic carbon with a surface area of similar to 680 m(2) g(-1) was produced. (C) 2001 Elsevier Science Ltd. All rights reserved.
