Abstract
An improved carbonaceous heat source suitable for use in a smoking article is provided. The heat source is formed by mixing a carbon component, a catalytic precursor and a binder, forming the mixture into a shape, and supplying heat to the mixture. Upon combustion of the heat source, the catalytic precursor forms a catalyst that converts carbon monoxide produced during combustion of the heat source into a benign substance.
