Smoking article
First Claim
1. A fuel element for a smoking article comprising:
- an outer shell of a carbonaceous material and an inner core of carbonaceous material, the outer shell surrounding the inner core;
coarse, fine or ultrafine particles of cerium oxide; and
a metal halide,wherein the carbonaceous material of the inner core is in intimate contact with both the coarse, fine or ultrafine particles of cerium oxide and the metal halide.

Abstract
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.

16. A method for making a fuel element for a smoking article, comprising:
-
forming a rod of an outer shell of carbonaceous material and an inner core of carbonaceous material, the outer shell surrounding the inner core; applying cerium oxide particles to the carbonaceous material, wherein the particles have a size less than about 100 nm; and applying a metal halide to the carbonaceous material such that the carbonaceous material of the inner core is in intimate contact with both the coarse, fine or ultrafine particles of cerium oxide and the metal halide. - View Dependent Claims (17, 18, 19, 20, 21)
