Abstract:
Cut filler compositions, cigarettes, methods for making cigarettes and methods for smoking cigarettes are provided, which involve the use of a composite mesoporous/microporous material. The composite material is capable of removing at least one constituent from tobacco smoke, preferably selectively. The composite material may also be used for removing at least one constituent from tobacco smoke through sorption and/or catalysis. The composite material comprises channels interconnecting at least one mesoporous region and at least one microporous region. The mesopores of the composite material may further comprise a carbon lining and/or be further functionalized with a surfactant. Alternatively, the composite material may further comprise a metal, a metal oxide, or mixtures thereof.
