Abstract

PURPOSE:To efficiently decompose NOx contained in exhaust gas by providing a catalyst carried with the specified amount of metal of platinum group such as Pt and Pd on composite oxide shown in the specified crystal structural formula to the passage of exhaust gas of an automobile equipped with an internal combustion engine. CONSTITUTION:Composite oxide having a crystal structure shown in a formula I (A and A' show alkaline earth metal, B and B' show rare earth metal, C and C' show metal of copper group and the other metal, 0<=x<=3.0, 0<=x'<=3.0, 0<=y<=2.0, 0<=y'<=2.0, 0<=z<=4.0, 0<=z'<=4.0, 4.0<=alpha<=8.0, 0<=beta<=2.0) is molded. Then an NOx decomposition catalyst is obtained by carrying 0-1wt.% metal of platinum group such as Pt and Pd on this composite oxide. The catalyst for purifying exhaust gas is constituted by providing this NOx decomposition catalyst 3 to the passage of exhaust gas of an automobile equipped with an internal combustion engine 1.
