Cigarettes and cigarette components containing nanostructured fibril materials

A method of making a cigarette, comprising:

• (i) depositing nanostructured fibrils on or incorporating nanostructured fibrils in at least one of tobacco cut filler and cigarette paper, wherein said nanostructured fibrils have an aspect ratio of length to width of greater than about 10:1, and wherein said nanostructured fibrils comprise manganese, iron and copper, oxides and/or oxyhydroxides of manganese, iron and copper, and mixtures thereof, or 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;
• (ii) providing the tobacco cut filler to a cigarette making machine to form a tobacco column;
• and
• (iii) placing the cigarette paper around the tobacco column to form a tobacco rod of a cigarette.
