High-pressure hydrogenated carbon nanofibers

Abstract High-pressure hydrogenation of the single-walled carbon nanotubes, graphite nanofibers and fullerenes C60 was developed. Produced samples have been studied by their combustion, gas thermodesorption, mass-spectroscopy, X-ray, IR and Raman scattering spectroscopes.

The carbon nanofiber (CNF) synthesis was performed at atmospheric pressure at temperatures ranging from 550 to 650 °C and under various matures of ethane and hydrogen. After synthesis the material was cooled to room temperature under the synthesis mixture and then discharged. Due to the high carbon nanofiber yield no post-treament was needed as usually encountered with other preparation methods such as acidic treatments in order to remove the metal catalyst from the final product.
