Abstract

A catalyst and method is provided for reducing pollutants in gases. The catalyst is composed of two substances. A first material which is an adsorption material has an adsorbent effect on an additional substance, the additional substance often being a hydrocarbon, such as propene. A second material is an oxidation material. The oxidation material has an oxidizing effect on the pollutant. The adsorption material and the oxidation material are on the same catalyst.
