Manufacturing method of NOx storage reduction catalyst |
| abstract |
The present invention relates to a method for producing a NOx storage reduction catalyst. [Problem] An object of the present invention is to provide a method for producing a NO x storage reduction catalyst capable of suppressing degradation of NO x purification performance after high temperature endurance. [Means for Solving] The present invention solves the above-mentioned problem by including (A) using potassium-dispersed water containing potassium compound particles and supporting the potassium compound particles on catalyst carrier particles in a method for producing a NOx storage reduction catalyst. , (B) calcining the catalyst carrier particles carrying the potassium compound particles; the potassium compound particles are selected from oteracil potassium, potassium tetranitroacridone, potassium tetraphenylborate and tetranitrophene At least one of thiazine-9-potassium oxide. |
