摘要：NOVELTY - The nano carbon fibre/ graphite felt composite catalysis material of a macroscopic dimension and the method for preparation. The composite catalysis material comprises graphite felt, and nano carbon fibre that grows on graphite felt in situation. The technique contains the following steps: liquid-phase or gas-phase oxygenizing graphite felt; soaking the treated graphite felt into water solution containing soluble metallic salt, heating in air condition; heating to 773- 973K in reduction condition and keeping 1-6h, then adding reactivity gas to generate the nano carbon fibre growing reaction on graphite felt in situation. The nano carbon fibre/ graphite felt composite material has a big density, a high mechanical strength, a hollow feature, and a large external surface area, and as a new carbonaceous catalysis material, it is suit for a catalyst carrier, or a catalyst.
