Abstract

PURPOSE:To improve heat resistance and to enable decomposition of NOx contained in large excess oxygen by carrying the specified amount of metal of platinum group such as Pt and Pd on composite oxide shown in the specified crystal structural formula to form an NOx decomposition catalyst. CONSTITUTION:An NOx decomposition catalyst is molded by carrying 0-1wt.% metal of platinum group such as Pt and Pd on composite oxide having a crystal structure shown in the formula I (A shows alkaline earth metal, B shows rare earth metal, C shows metal of copper group, 0<=x<=3.0, 0<=y<=2.0, 0<=z<=4.0, 4.0<=alpha<=8.0, 0<=beta<=2.0). This 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 is molded into a honeycomb shape.
