Catalyst and method of preparing the catalyst
First Claim
1. A method of preparing a catalyst comprising a composition containing Mn oxide, metal Pd and/or Pd oxide formed as a thin film on a support which comprises mixing Mn oxide, metal Pd and/or Pd compound and water, heating and subsequently cooling the mixture, adding an inorganic oxide sol as a binder forming the mixture into a slurry, dipping a support into the slurry and removing the support therefrom, removing deposited excess slurry by pressurized air, and drying and baking the coated support to form said catalyst.

Abstract
The catalyst accordidng 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 deomposing offensive odor ingredients contained in a gas by catalytic oxidation under the pretense of ozone, and it comprises a composition containing Mn oxide, metal Pd and/or Pd oxide 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.
