1s2p Resonant inelastic X-ray scattering of iron oxides

Article Abstract:

1s2p Resonant inelastic X-ray scattering (RIXS) spectroscopy is measured for a series of iron oxides, including octahedral and tetrahedral Fe(super II) and Fe (super III) systems, crystal-field multiplet simulations are used to analyze their spectral shapes. The full power and possibilities of 1s2p RIXS needs an overall resolution of 0.3 eV and this yields a technique with more detailed information than K-edge and L-edge X-ray absorption combined, obtained in a single experiment.

In situ X-ray absorption of Co/Mn/TiO2 catalysts for Fisher-Tropsch synthesis

Article Abstract:

The reduction behavior of Co/TiO2 and Co/Mn/TiO2 catalysts for Fisher-Tropsch synthesis is investigated. Catalytic tests in the Fisher-Tropsch synthesis reaction at the pressure of 1 bar indicate that the selectivity of these catalysts might be related to the extent of Co reduced after the activation treatment.

In-Situ soft X-ray absorption of over-exchanged Fe/ZSM5

Article Abstract:

In-situ soft X-ray absorption spectroscopy (XAS) is applied to study the iron redox behavior in over-exchanged Fe/ZSM5. The tool claims to provide new information on the geometry and valence of the Fe sites and yields an accurate method to determine the average iron valence during oxidation/reduction cycles.
