摘要： It is an object of the present invention to provide an exhaust gas purifying catalyst formed as a single catalyst that has a great deal of flexibility when being assembled into an exhaust system and that is capable of executing both an NOx absorbing function and a three-way function in a desired manner. To attain the this object, an absorbent catalyst layer to which an absorbent agent such as potassium and an acid material such as zeolite are added, an absorbent agent block layer formed of zeolite, and a three-way catalyst layer to which an acid material such as phosphorus is added are bonded together on a cordierite carrier. The acid material in the absorbent catalyst layer and the absorbent agent block layer inhibit the movement of the absorbent agent to the three-way catalyst layer, and transform the absorbent agent into harmless and stable potassium phosphate even if the absorbent agent reaches the three-way catalyst.

摘要： In an exhaust gas purifying catalyst, an acid material with a high affinity with respect to an absorbing agent is dispersed and mixed in a catalyst layer, to which the absorbing agent is added, or a layer of the acid material is formed inside the catalyst layer in order to prevent the absorbing agent from moving from the catalyst layer into the carrier. This reduces the permeation of the absorbing agent added to the catalyst layer into a carrier, the evaporation and splash of the absorbing agent from the catalyst, and the deterioration in the durability and the exhaust gas purifying performance of the catalyst.
