Abstract

Compositions à base de tabac de remplissage, papier à cigarettes, filtres de cigarettes, 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. Ce catalyseur comporte des particules nanométriques de métal et/ou d'oxyde métallique portées par des particules véhicules à grande surface spécifique. La préparation du catalyseur peut consister à associer une solution de précurseur métallique à des particules véhicules à grande surface spécifique de manière à former un mélange, ou à associer une solution de précurseur métallique à une solution colloïdale de manière à former un mélange, puis à réaliser un traitement thermique du mélange.
