Abstract

The present invention provides fuel elements (10) comprising a carbonaceous material and a catalyst composition comprising ultrafine particles of a metal oxide and/or metal. The present invention additionally provides smoking articles demonstrating reduced amounts of carbon monoxide in the smoke-like aerosol produced by the smoking article. In a further aspect, the present invention provides methods and apparatus for the simultaneous resolution and quantification of a carbon monoxide content and a carbon dioxide content of a gaseous mixture.
