摘要
A method for the catalytic removal of nitric oxide and carbon monoxide from tobacco smoke which comprises contacting the smoke with a compound of the formula M2M'RuO6 wherein M is a divalent metal, M' is a trivalent rare earth metal, and Ru has a valence of 5, M and M' being such that their ions are capable of forming a perovskite lattice with the Ru ions. The catalyst can be mixed with tobacco, or incorporated into the cigarette paper or filter. Optionally, suitable inorganic or organic adsorbing materials are desirable; e.g. carbon and calcium carbonate.
