Reduction of nitrogen oxide by carbon monoxide in the presence of oxygen, with a palladium catalyst supported on fresh and aged alumina
Abstract
The reduction of nitrogen oxide with carbon monoxide in presence of oxygen over a palladium based catalysts is studied. Metal dispersion decreases with the thermal aging of the fresh solid in a wet and oxidant atmosphere. However, the aged solid shows a catalytic activity for the oxidation of carbon monoxide and the reduction of nitrogen oxide higher than the fresh solid. After reaction, particle sizes and surface state were determined. The state of oxidation and the kind of surface oxide are different for the fresh and aged solids.
