ABSTRACT:
The catalyst according to the present invention can be utilized effectively as an ozone decomposing catalyst for catalytically decomposing to eliminate ozone contained in a gas and/or an ozone deodorizing catalyst for decomposing offensive odor ingredients contained in a gas by catalytic oxidation under the pretense of ozone, and it contains at least manganese carbonate as the essential component in the catalyst composition. Further, the catalyst contains, particularly preferably, MnO.sub.x (in which x=1.6-2.0) in addition to manganese carbonate and such a catalyst is obtained by applying a heat treatment to a catalyst raw material containing manganese carbonate in an oxidative atmosphere at 100.degree.-420.degree. C.
