ABSTRACT:
A method for catalytically reducing pollutants, in particular oxides of nitrogen in oxygen-containing exhaust gases of internal combustion engines, uses a catalyzer unit arranged in the exhaust gas flow of the engine. The catalyzer unit has a catalytic layer, an ion conducting layer and a counterelectrode. The catalytic layer exhibits a non-Faraday modification of the catalytic activity.
