Abstract
Tobacco products and articles are disclosed that include a nanoparticle catalyst. The nanoparticles are capable of degrading undesirable small molecules in tobacco smoke. The nanoparticle catalyst includes a dispersing agent that inhibits the deactivation of the nanoparticle catalyst. One embodiment disclosed has a dispersing agent that anchors the nanoparticles to a support material thereby preventing agglomeration of the nanoparticles. The dispersed nanoparticles exhibit higher activity and reduce the required loading in the tobacco material.
