Patent ID: 7856992

Claim:
A tobacco composition for generating tobacco smoke with reduced amounts of undesirable small molecules, including a reduced amount of nitric oxide compared to combustion of untreated tobacco material, the tobacco composition comprising: a tobacco material; and a catalyst composition on a support material, the catalyst composition comprising: a plurality of active atoms dispersed to form nanoparticles having a size less than about 100 nm and being capable of reducing the concentration of at least one type of undesirable small molecule in tobacco smoke; and a dispersing agent comprising at least one functional group selected from the group consisting of a hydroxyl, a carboxyl, a thiol, a sulfonic acid, a sulfonyl halide, a carbonyl, an amine, an amide, an amino acid, an acyl halide and combinations thereof, wherein the dispersing agent is bound to the nanoparticles, anchors the nanoparticles to the support material, and inhibits agglomeration of the nanoparticles prior to use of the tobacco composition, the tobacco composition being configured so as to generate a reduced amount of nitric oxide upon combustion compared to combustion of untreated tobacco material.
