PURPOSE:To form a complete perovskite structure by depositing a specified amt. of an iron element on a catalyst consisting of an inorg. heat-resistant material, and then depositing a specified amt. of a perovskite type composite oxide to obtain the titled catalyst. CONSTITUTION:An inorg. heat-resistant material such as alumina, silica, and cordierite is formed into a honeycomb, a foamed ceramic, or a cloth to obtain a catalyst carrier. From 1-15wt% iron element is deposited on the catalyst carrier. The perovskite type composite oxide is expressed by the crystal structural formula ABO3, the A site is selected from >=1 kind of element among alkaline earth metals such as strontium and calcium, and the B site is formed with a cobalt element. Then 1-15wt% perovskite type composite oxide is deposited to produce the perovskite type oxidation catalyst. |
