<p>PURPOSE:To obtain an ozone decomposing efficiency and excellent durability, by compounding Co-oxide, ni-oxide and Mn-oxide in a specific containing ratio. CONSTITUTION:This catalyst comprises three components, that is, Co-oxide (CoOx), NO and MnO2 and, with respect to the contents of the aforementioned components, CoOx is adjusted to 48-80mol%, NiO to 10-38mol% and MnO2 to 2-22mol%. As the result, an ozone decomposing catalyst having both high ozone decomposing efficiency and excellent durability not achieved by a CoRx catalyst or a CoOx-NiO catalyst is obtained. This catalyst can be prepared by a kneading method, a suspension precipitation method or the like. In addition, the shape of the catalyst may be a fine powder, a granule or a pellet having an arbitrary particle size, one obtained by coating the surface of a monolithic ceramic carrier with a catalyst or other shapes.</p> |
