Nanoscale catalyst particles/aluminosilicate to reduce carbon monoxide in the mainstream smoke of a cigarette |
摘要 |
A smoking article composition and a method of making a smoking article composition comprising tobacco cut filler, cigarette paper and/or cigarette filter material further comprising a catalyst capable of converting carbon monoxide to carbon dioxide, wherein the catalyst comprises nanoscale catalyst particles dispersed within a porous aluminosilicate matrix. The catalyst can be formed by combining nanoscale catalyst particles or a metal precursor solution thereof with an alumina-silica sol mixture to form a slurry, gelling the slurry to form the co-gel, heating the co-gel to form a catalyst comprising nanoscale catalyst particles dispersed within a porous aluminosilicate matrix. The catalyst can be incorporated in tobacco cut filler, cigarette paper and/or cigarette filter material by spraying, dusting and/or immersion.
