Abstract
PURPOSE:To enhance heat resistance and to enable decomposition of NOx contained in large excess oxygen without using a reducing agent by forming an NOx decomposition catalyst having a structure such as a perovskite type shown in the specified crystal structural formula. CONSTITUTION:An NOx decomposition catalyst having a crystal structure shown in a formula I (A shows alkaline earth metal such as Ba and Sr, B shows rare earth metal such as Y, Nd and La, C shows metal of copper group such as Cu and Ag, 0<=x<=3.0, 0<=y<=2.0, 0<=z<=4.0, 4.0<=alpha<=8.0, 0<=beta<=2.0) is molded. This NOx decomposition catalyst is obtained by carrying the above-mentioned composite oxide together with an inorganic binder such as colloidal alumina on the surface of a catalyst carrier wherein an inorganic heat resistant material such as alumina and silica is molded into a honeycomb shape.
