Catalyst and a method of preparing the catalyst.

摘要

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 or as an ozone deodorizing catalyst for decomposing offensive odor ingredients contained in a gas by catalytic oxidation under the presence of ozone, and it comprises a composition containing Mn oxide, metal Pd and/or Pd compound as the essential ingredients formed as a thin film on a support. Further, the performance of the catalyst can be improved by using Mn oxide and Pd as the essential ingredient and using an alumina sol as a binder upon preparation.
