Abstract
La présente invention concerne, à titre principal, un procédé pour préparer des nanotubes de carbone (NTC) multi-paroi dopés (MWCNT acronyme anglais de « Multi Wall Carbon Nano Tubes ») au soufre par une technique CVD, mettant en œuvre la décomposition thermique d'un flux gazeux, source en carbone et en soufre, au contact de la forme réduite d'un catalyseur métallique, caractérisé en ce que, préalablement à sa mise en contact avec ledit flux gazeux, source en carbone et en soufre, ledit catalyseur est mis en contact avec un flux gazeux qui contient au moins un composé hydrocarboné et est exempte de composé source en hétéroatome, dans des conditions propices à l'amorçage de la croissance de nanotubes de carbone. Elle vise en outre des nanotubes de carbone (NTC) multi-paroi dopés au soufre conformes à l'invention.The present invention mainly relates to a process for preparing multi-wall carbon nanotubes (CNTs) doped (MWCNT for “Multi Wall Carbon Nano Tubes”) with sulfur by a CVD technique, using thermal decomposition. of a gas stream, source of carbon and sulfur, in contact with the reduced form of a metal catalyst, characterized in that, prior to its contact with said gas stream, source of carbon and sulfur, said catalyst is brought into contact with a gas stream which contains at least one hydrocarbon compound and is free from heteroatom source compound, under conditions conducive to the initiation of the growth of carbon nanotubes. It also relates to multi-wall carbon nanotubes (CNTs) doped with sulfur in accordance with the invention.
