Abstract
High temperature treatment of graphite nanofibers to increase their catalytic activity. The heat treated graphite nanofiber catalysts are suitable for catalyzing chemical reactions such as oxidation, hydrogenation, oxidative-dehydrogenation, and dehydrogenation.
Claims9
A catalytic chemical reaction selected from oxidation, hydrogenation, dehydrogenation, oxidative-hydrogenation, and oxidative-dehydrogenation which is catalyzed by a catalyst composition comprised of graphitic nanofibers which nanofibers are comprised of a plurality of graphite platelets aligned at an angle from about 1° to about 90° with respect to the longitudinal axis of the nanofibers and which nanofibers have a crystallinity greater than about 90%, which method comprises heat treating said nanofibers in an inert gas environment at temperatures from about 2300° C. to about 3000° C.
