Popis:	In situ X-ray diffraction and differential thermal analysis have been applied to a study of a supported oxide catalyst used in the air oxidation of CO to CO2. Studies have been made of a given catalyst that has been activated to several different metastable states. The X-ray studies under reaction conditions reveal pronounced differences in composition for the variously activated catalysts. Activation involves reduction to Cu2O and Cu, and the formation of lattice heterogeneities. The active sites of the metastable catalysts studied are associated with the interface between Cu1+ and Cu0 phases, and/or nonstoichiometric Cu2O and Cu phases. The X-ray results under reaction conditions differ from these obtained at ambient conditions.
