Abstract

Fibrous nanocarbons were synthesized at low temperature by catalytic decomposition of hydrocarbons and carbon monoxide. They were then characterized by micro-structural and electrochemical techniques. It was found that the as-prepared nanocarbons could be classified into platelet, herringbone and tubular morphologies. The highest tap densities (70-90%) were observed for platelet morphologies. These were comparable with conventional graphite, and correlated with the high degree of graphitization that is associated with fast reduction in a H2/He flow. The electrochemical discharge profiles of the platelet morphologies were similar to that of material graphitized at >2400 °C. Such materials may be acceptable alternatives to conventional synthetic graphites.
