Operando XAFS study of catalytic NO reduction over Cu/CeO2: the effect of copper-ceria interaction under periodic operation.
نویسندگان
چکیده
Using an operando time-resolved XAFS technique at the Cu and Ce K-edges, we have discovered that the synchronization of Cu and Ce valence change in Cu/CeO2 under periodic (rich-lean cycling) operation can improve the catalytic activity for NO reduction at low temperature.

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 a novel reversed microemulsion method (doped Ce1-xCuxO2 sample) and an impregnation method (impr...

متن کاملMorphological effects of the nanostructured ceria support on the activity and stability of CuO/CeO2 catalysts for the water-gas shift reaction.
Three CuO/CeO2 catalyst with different morphologies of ceria, namely nanospheres, nanorods and nanocubes, were synthesized and used to catalyze the water-gas shift (WGS) reaction. The reactivity tests showed that the Cu supported on the ceria nanospheres exhibited both the highest activity and superior stability when compared with the nanocube and nanorod ceria catalysts. Operando X-ray diffrac...
