Structural characterization of CeO2-TiO2 and V2O5/CeO2-TiO2 catalysts by Raman and XPS techniques

Article Abstract:

The structural characterization of ceria-titania and vanadia/ceria-titinia mixed oxides were investigated using x-ray powder diffraction (XRD), Raman spectroscopy (RS), and X-ray photoelectron spectroscopy (XPS) techniques. The XRD and RS results provide direct evidence about the formation of CeVO4 and the XPS electron-binding energies indicate that ceria, titania and vanadia are mainly in their highest oxidation states.

Reaction pathways and site requirements for the activation and chemical conversion of methane on Ru-based catalysts

Article Abstract:

The isotopic studies and forward reaction rate measurements are used to determine the identity and reversibility of elementary steps required for CH4 reforming reactions on Ru-based catalysts. This provides a simple mechanistic picture and a unifying kinetic treatment for Ch4/H2O reforming reactions and CH4 decomposition.
