Abstract

L'invention concerne un procédé de production de nanofibres de carbone graphitique sensiblement cristallin constituées de feuilles de graphite. Les feuilles de graphite sont sensiblement parallèles ou sensiblement perpendiculaires à l'axe longitudinal de la nanofibre de carbone. Lorsque les feuilles de graphite doivent être sensiblement parallèles, ces nanofibres de carbones sont produites par mise en contact de catalyseur en masse à base de fer ou bimétallique à base de fer:cuivre, ou de fer:nickel, avec un mélange de monoxyde carbone et d'hydrogène à des températures comprises entre 670 ·C environ et 725 ·C environ pendant une durée effective. Lorsque les feuillets de graphite doivent être sensiblement perpendiculaires, les nanofibres sont produites par l'utilisation d'un catalyseur en masse bimétallique fer:cuivre à des températures comprises entre 550 ·C environ et 670 ·C environ.
