ABSTRACT:
Ozone is catalytically removed from air at room temperatures. Air containing ozone in dilute concentrations is contacted with a catalyst formed of a; palladium (II) salt such as palladium (II) chloride, a copper (II) slat such as copper (II) chloride and copper (II) sulfate, and a nickel (II) salt such as nickel (II) chloride, on an alumina substrate, at a temperature in the range of -20.degree. C. to 85.degree. C. The catalyst is formed by making a paste of particulate alumina and a palladium (II) halide containing impregnating solution and then drying the paste and activating the catalyst by heating.
