Abstract
PURPOSE: To obtain a filter which can decompose and convert nitrogen oxides included in the fume of tobacco into harmless nitrogen by depositing platinum metals on a specified multiple oxide to prepare a decomposition catalyst for nitrogen oxides and disposing the catalyst in the passage of exhaust gas. CONSTITUTION: Platinum metals such as Pt and Pd are deposited by 0 to 1 % on a multiple oxide having the crystal structural formula to prepare a decomposition catalyst 2 for nitrogen oxides. The catalyst 2 is disposed in the passage of exhaust gas to obtain the filter of the purpose. In the formula. A represents alkaline earth metals such as Ba and Sr, B represents rare earth elements such as Nd and Cd, C represents copper metals such as Cu and Ag, numbers x, y, z, α, β satisfy 0<=x<=3.0, 0<=y<=2.0, 0<=z<=4.0, 0<=α<=8.0, 0<=β<=2.0.
