Method for treating atmospheric pollutants by contacting the atmosphere with a catalyst composition or adsorptive material coated on the surface of a substrate, preferably a motor vehicle radiator, in which the catalyst composition, preferably including a base metal, precious metal, or salts/oxides

Method for treating atmospheric pollutants by contacting the atmosphere with a catalyst composition or adsorptive material coated on the surface of a substrate, preferably a motor vehicle radiator, in which the catalyst composition, preferably including a base metal, precious metal, or salts/oxides thereof, or adsorptive material, preferably including a zeolite, Group IIA alkaline earth metal oxide or carbon, is protected from degradation by harmful contaminants such as solid or aerosol particulates, water, SOx, NOx and water borne salts contained in the atmosphere by a coating of at least one porous protective material and a device useful therefor.
