Abstract
Supported catalyst particles, which can be incorporated in the tobacco cut filler, cigarette wrapper and/or cigarette filter of a cigarette, are useful for low-temperature and near-ambient temperature catalysis of carbon monoxide and/or nitric oxide. 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.
