Title
(EN) METHOD FOR PREPARING METAL-FREE NITROGEN-CONTAINING CARBON NANOTUBES
(FR) PROCÉDÉ DE PRÉPARATION DE NANOTUBES DE CARBONE CONTENANT DE L'AZOTE ET EXEMPTS DE MÉTAL
Abstract
(EN)
The present invention relates to a method for preparing metal-free nitrogen-containing carbon nanotubes (NCNTs) having a core/shell structure, in which the core is composed of carbon and the shell is mainly composed of carbon and nitrogen. The invention also relates to metal-free nitrogen-containing carbon nanotubes (NCNTs) obtainable by said method and to their use as a catalyst for oxygen reduction reactions, notably in alkaline media in fuel cells.
(FR)
La présente invention concerne un procédé de préparation de nanotubes de carbone contenant de l'azote (NCNT) et exempts de métal, ayant une structure cœur/écorce, dans laquelle le cœur est composé de carbone et l'écorce est principalement composée de carbone et d'azote. L'invention concerne également des nanotubes de carbone contenant de l'azote (NCNT) et exempts de métal, pouvant être obtenus au moyen dudit procédé, et leur utilisation comme catalyseur intervenant dans des réactions de réduction d'oxygène, notamment dans des milieux alcalins de piles à combustible.
