Abstract
Nanoscale particles are formed and deposited in situ on tobacco cut filler, cigarette paper and/or cigarette filter materials by physical vapor deposition. The nanoscale particles are 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.
