A smoking article, such as a cigarette, includes a carbonaceous heat source. A mouth end piece segment is located at the mouth end of the smoking article, and the mouth end piece segment allows the smoking article to be placed in the mouth of the smoker to be drawn upon. The smoking article further incorporates an aerosol-generating segment located between the heat generation segment and the mouth end piece segment. The aerosol-generating segment incorporates an aerosol-forming material (e.g., glycerin and flavors). The heat generation segment is in a heat exchange relationship with the aerosol-generating region such that heat generated by the burning fuel element acts to volatilize aerosol-forming material for aerosol formation. The carbonaceous heat source is in intimate contact with coarse, fine or ultrafine particles of materials such as cerium oxide, or mixtures of cerium oxide and palladium chloride.
