Abstract

L'invention porte sur un composant de la cigarette qui comprend un catalyseur à base d'argent intervenant dans la conversion du monoxyde de carbone en dioxyde de carbone. Le catalyseur à base d'argent comprend des particules (telles que des particules à échelle nanométrique ou de plus grande taille) d'argent métallique et/ou d'oxyde d'argent supportées dans et/ou sur des particules de support d'oxyde métallique. Le catalyseur à base d'argent peut être incorporé dans un composant de la cigarette tel que le tabac haché, le papier de cigarette et le filtre de cigarette afin de réduire la concentration du monoxyde de carbone dans la fumée principale d'une cigarette. Le catalyseur peut également être utilisé dans des applications autres que la cigarette
