Abstract (en)
[origin: FR2909989A1] Catalyst material (I) for the production of multi-shell carbon fibrils and nanotubes (II), comprises one or more multivalent transition metals and a solid organic substrate. Independent claims are also included for (1) a method (M1) for the production of (I) by bringing an organic substrate into contact with a solution of transition metal salt(s), preferably under a current of dry gas (2) a method (M2) for the production of multi-shell carbon fibrils and nanotubes (II) by (a) making catalyst material (I) as above with a BET surface of less than 200 (preferably 0.1-50) m2>/g, (b) growing (II) by thermal decomposition of the organic substrate by heating (I) at 300-1200[deg] C in presence of gas containing at least 20% hydrogen, and then (c) cooling the product .
