  • Ozone abatement catalyst having improved durability and low temperature performance
    Patent number: 4405507
    Abstract: Precious metal ozone decomposition catalyst, its stabilization and method for decomposing ozone for purification and detoxification purposes by contacting with a decomposition catalyst containing a platinum group metal and a nonprecious Group VIII metal oxide or aluminate on a support, favoring exposure to ozone of the platinum group metal over the nonprecious metal oxide or aluminate, the arrangement favoring maximum conversion per unit volume and system pressure drop by catalytic element configuration within a given catalyst volume.
