A device (100) for producing fullerenes includes an IEC vacuum chamber (110) which has a central grid-like electrode (112) and a conductive outer shell (111) that are connected to a pulsed source of high voltage (114) and provide an electric field within the chamber (110). The applied voltage supports the creation of a plasma at the inner core of the chamber near the electrode (112). A carbon-based gas, which is introduced into the chamber (110), possibly along with an inert buffer gas, is dissociated into component carbon and hydrogen ions that are separated and the carbon ions recombined into fullerenes that appears as a soot. The device (100) includes a soot extraction mechanism for removing and collecting the fullerenes.

Cette invention concerne un dispositif (100) qui permet de produire des fullerènes, et qui comprend une chambre sous vide de chromatographie par échange ionique (110). Cette chambre comprend une électrode centrale de type grille (112) ainsi qu'une enceinte externe conductrice (111), lesquelles sont connectées à une source de haute tension pulsée (114) et vont générer un champ électrique à l'intérieur de ladite chambre (110). La tension ainsi appliquée va assurer la formation de plasma au niveau du noyau interne de la chambre et à proximité de l'électrode (112). Un gaz à base de carbone, qui est introduit dans la chambre (110) de préférence en même temps qu'un gaz tampon inerte, va se dissocier en ions constituants carbone et hydrogène distincts. Les ions carbones sont ensuite recombinés en fullerènes qui se présentent sous forme de suies. Ce dispositif (100) comprend également un mécanisme d'extraction des suies qui permet de retirer et de récupérer les fullerènes.
