Cut filler compositions, cigarettes, methods for making cigarettes and methods for smoking cigarettes which involve the use of partially reduced nanoparticle additives capable of acting as an oxidant for the conversion of carbon monoxide to carbon dioxide and/or as a catalyst for the conversion of carbon monoxide to carbon dioxide are provided. The compositions, articles and methods of the invention can be used to reduce the amount of carbon monoxide and/or nitric oxide present in mainstream smoke. The partially reduced additive can be formed by partially reducing Fe2O3, to produce a mixture of various reduced forms such as Fe3O4, FeO and/or Fe, along with unreduced Fe2O3.
L'invention concerne des compositions de tabac haché, des cigarettes, des procédés de fabrication de cigarettes, ainsi que des procédés de consommation de cigarettes, consistant à utiliser des additifs partiellement réduits sous forme de nanoparticules agissant en tant qu'oxydant dans la conversion du monoxyde de carbone en dioxyde de carbone et/ou en tant que catalyseur dans la conversion du monoxyde de carbone en dioxyde de carbone. Les compositions, articles et procédés selon l'invention peuvent être utilisés pour réduire la quantité de monoxyde de carbone et/ou d'oxyde nitrique présent dans la fumée principale. Les additifs partiellement réduits selon l'invention peuvent être formés par réduction partielle de Fe¿2?O¿3?, de sorte à produire un mélange de formes réduites diverses, telles que Fe¿3?O¿4?, FeO et/ou Fe, avec Fe¿2?O¿3? non réduit.
