Cut filler compositions, cigarettes, methods for making cigarettes and methods for smoking cigarettes are provided, which involve the use of a catalyst capable converting carbon monoxide to carbon dioxide and/or nitric oxide to nitrogen. Cut filler compositions comprise tobacco and at least one catalyst. Cigarettes are provided, which comprise a cut filler having at least one catalyst. The catalyst comprises nanoscale metal and/or metal oxide particles supported on a fibrous support. The catalyst can be prepared by combining a dispersion of nanoscale particles with a fibrous support, or by combining a metal precursor solution with a fibrous support and then heat treating the fibrous support.
Compositions à base de tabac de remplissage, cigarettes, procédés de fabrication de cigarettes et procédés pour fumer les cigarettes, comprenant l'utilisation d'un catalyseur apte à transformer le monoxyde de carbone en gaz carbonique et/ou le monoxyde d'azote en azote. Les compositions à base de tabac de remplissage comportent du tabac et au moins un catalyseur. On a également prévu des cigarettes comportant un tabac de remplissage renfermant au moins un catalyseur. Ce catalyseur comporte des particules nanométriques de métal et/ou d'oxyde métallique portées par un support fibreux. La préparation du catalyseur peut consister à associer une dispersion de particules nanométriques à un support fibreux, ou à associer une solution de précurseur métallique à un support fibreux, puis à réaliser un traitement thermique du support fibreux.
