CATALYSTS FOR THE OXIDATION OF CARBON MONOXIDE IN CIGARETTE SMOKE

摘要

A component of a cigarette comprises a silver-based catalyst for the conversion of carbon monoxide to carbon dioxide, the catalyst comprises agglomerates of nanoscale silver-based particles, in and/or on support particles of an oxide of a second metal, the second metal being different than silver, wherein the agglomerates have an average size of from about 1 to 50 microns, wherein the component is selected from the group consisting of tobacco cut filler, cigarette paper and cigarette filter material. The catalyst can be incorporated into a cigarette component reduce the concentration of carbon monoxide in the mainstream smoke of a cigarette during smoking. A method is also proposed of making a cigarette using said catalyst. The catalyst can also be used in noncigarette applications.
