Abstract
Cigarette paper, methods for making cigarettes and methods for smoking cigarettes are provided, which involve the use of an oxyhydroxide 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 and/or as a catalyst for the conversion of carbon monoxide to carbon dioxide. The oxyhydroxide compound and/or the product formed from the decomposition of the oxyhydroxide can be in the form of nanoparticles. The oxyhydroxide compounds can be represented by MOOH where M is a metal selected from the group consisting of transition metals, rare earth metals, and mixtures thereof.
