ABSTRACT:
A wrapper for a smoking article includes nanoparticle spinel ferrite catalyst and a web including cellulosic fibers and an optional web-filler. The web-filler can be a modified web-filler which incorporates the spinel ferrite catalyst. The nanoparticle spinel ferrite catalyst can be a nanoparticle manganese-copper-iron oxide catalyst incorporated in the wrapper and/or a tobacco cut filler. Also provided is a smoking article including a cigarette tobacco rod having a wrapper including a web, a web-filler, and a nanoparticle spinel ferrite catalyst, the web-filler optionally supporting the nanoparticle catalyst. A method of making the wrapper and a method of making a smoking article utilizing the wrapper are also provided.
