In Situ Studies of the Active Sites for the Water Gas Shift Reaction over Cu−CeO2 Catalysts:  Complex Interaction between Metallic Copper and Oxygen Vacancies of Ceria

New information about the active sites for the water gas shift (WGS) reaction over Cu−CeO2 systems was obtained using in-situ, time-resolved X-ray diffraction (TR-XRD), X-ray absorption spectroscopy (TR-XAS, Cu K and Ce L3 edges), and infrared spectroscopy (DRIFTS). Cu−CeO2 nanoparticles prepared by...
