1 GALLAHER LIMITED GJE 678/17 SMOKING PRODUCTS ABSTRACT Catalysts are described that have particularly good activity when used in smoking products, or filters for smoking products, for oxidising carbon monoxide to carbon dioxide. Smoking products or filters for smoking products containing such catalysts are described. The catalyst may include mixtures of tin or tin compound with other catalytic material. The catalysts may involve a redox mechanism. Particularly valuable results are obtained when a redox catalyst is made by first depositing a major amount of one component of the catalyst and then a minor amount of the other component.
