A heat-conducting tobacco composition comprising at least one sort of tobacco in at least one confectioning of the tobacco for smoking tobacco consumption. The heat-conducting tobacco composition is configured or designed as a tobacco article for at least one smoking article selected from the following group: dry tobacco article for cigarettes, cigarillos, cigars, semi-dry tobacco article for smoking tobacco pipes, moist tobacco article for water pipes; wherein the heat-conducting tobacco composition further comprises at least one metallic, in particular noble metallic component which performs a physical heat-conducting function during smoking, in particular when exposed to heat by ember/glow or by heating elements of the smoking article, and which is chemically inert at least in the temperature range required for smoking, and which is admixed to the tobacco and distributed in the tobacco composition in such a way that the heat distribution within the tobacco composition is homogenized during smoking.

The invention provides a method for making a fuel element for a smoking article comprising forming a combustible carbonaceous material into a fuel element adapted for use in a smoking article; incorporating a metal-containing catalyst precursor into the fuel element or onto the surface thereof to form a treated fuel element, the incorporating step occurring before, during, or after said forming step; and optionally heating or irradiating the treated fuel element at a temperature and for a time sufficient to convert the catalyst precursor to a catalytic metal compound. Examples of metal-containing catalyst precursors include iron nitrate, copper nitrate, cerium nitrate, cerium ammonium nitrate, manganese nitrate, magnesium nitrate, and zinc nitrate. Fuel elements treated according to the invention, and smoking articles including such fuel elements, are also provided.

An article for use with a non-combustible aerosol provision device can include a continuous rod of aerosol-generating material and a coil disposed around the rod of aerosol-generating material. The coil can include heating material that is heatable by penetration with a varying magnetic field. A wrapper can be arranged to surround the aerosol-generating material and a coil can be disposed around the wrapper. The article can include a rolled sheet having a spiral cross-section, the rolled sheet including aerosol-generating material and a mesh including heating material that is heatable by penetration with a varying magnetic field. Also, an article can include a continuous rod of aerosol-generating material and one or more bodies disposed in an axial region of the rod, the axial region extending along the longitudinal axis of the rod, wherein the one or more bodies have a circular cross-section and have a diameter in the range 0.5 mm to 5 mm, and wherein the one or more bodies include heating material that is heatable by penetration with a varying magnetic field.

A wrapper for a smoking article includes a web; and a patterned deposit on at least a portion of one surface of the wrapper, wherein the patterned deposit comprises catalyst particles. The patterned deposit can include a nanoparticle catalyst that is capable of catalyzing the conversion of a constituent gas component in the mainstream and/or sidestream smoke of the smoking article. The constituent gas component can be carbon monoxide and/or nitric oxide and the catalyst particles can be iron oxide. Also provided is a smoking article comprising a tobacco rod having a wrapper formed around the tobacco rod, the wrapper including a patterned deposit on at least a portion of one surface of the wrapper. A method of making the wrapper and a method of making a smoking article utilizing the wrapper are also provided.

A method for oxidizing carbon monoxide to carbon dioxide is provided which utilizes specific supported catalyst particles. The supported catalyst comprises catalyst particles that are supported on particles of an electrically conductive support selected from the group consisting of graphitic carbon and a partially reduced oxide of a transition metal of the Magnli phase selected from the group consisting of titanium, vanadium, zirconium, niobium, molybdenum, and mixtures thereof.
