ABSTRACT:
A process for decreasing the air-sensitivity of a carbon monoxide oxidation catalyst composition is provided. The process can comprise, consist essentially of, or consist of (1) heating the composition at a temperature sufficient to produce an activated composition; (2) contacting the activated composition with an oxygen-containing fluid whereby a deactivated composition is produced; and (3) contacting the deactivated composition under reducing atmosphere and at a low temperature wherein the composition can comprise, consist essentially of, or consist of platinum, iron, and an inorganic support; or can comprise, consist essentially of, or consist of palladium, platinum, iron, and an inorganic support.
