Abstract
Carbon-nitrogen nanofibers are prepared by contacting a gaseous mixture comprising hydrogen and a carbon-nitrogen compound such as pyridine with a cobalt-iron catalyst at a temperature in the range of about 500-1000° C. The nanofibers are characterized by a structure in which layers emanate from a core catalyst particle and are parallel to each other but not parallel to the length axis of the nanofibers.
