Carbon nanofibre composites, preparation and use, EP application 04076211.4

Abstract

The invention is directed to a carbon nanofibre composite having a bulk density of at least 800kg/m3, obtainable by the process of growing carbon nanofibres on the surface of a supported carbon fibre producing metal catalyst, such as a catalyst based on nickel, cobalt, iron, ruthenium or combinations and/or alloys thereof, by decomposition of a hydrocarbon, for a sufficient period of time to produce the required bulk density, optionally followed by removal of the growth catalyst, to their production and use as catalyst support
