Abstract

Cut filler compositions, cigarettes, methods for making cigarettes and metho ds for smoking cigarettes are provided, which involve the use of an oxyhydroxid e compound that is capable of decomposing to form at least one product capable of acting as an oxidant for the conversion of carbon monoxide to carbon dioxide. The combustion zone of a cigarette during smoking (where Fe2O3 nanoparticles act as an oxidant) and the pyrolysis region of a cigarette during smoking (where the Fe2O3 nanoparticles act as a catalyst), as well as relevant reactions that occur in those regions.
