In this study an analysis strategy towards using the resonant inelastic X-ray scattering (RIXS) technique more effectively compared with X-ray absorption spectroscopy (XAS) is presented. In particular, the question of when RIXS brings extra informati

The chemical state of the Cu promoter (1 wt %) in a Cu-promoted Cr-stabilized iron oxide based water−gas shift catalyst has been studied by in-situ X-ray absorption fine structure (XAFS) at 380 °C and elevated pressures, which is close to the cond

Publikováno v: MRS Bulletin. 32:1038-1043

X-ray absorption fine structure (XAFS) spectroscopy probes the structure and electronic properties of metal centers. Because it can be applied to noncrystalline materials, it is a key technique for probing nanoparticulate materials, such as colloidal

Publikováno v: Journal of Catalysis. 225:86-94

The adhesion, shape, and electronic structure of gold particles supported on TiO 2 (110) have been determined by density-functional theory calculations, to gain more insight into the catalytic activity of small supported gold particles. These calcula

Publikováno v: Zeitschrift für Metallkunde. 94:1199-1205

High-energy synchrotron radiation has been used to study in situ annealing of cold-rolled Cu and Ti. The measurements were performed using a high-vacuum furnace in transmission geometry and an area detector. The diffraction images were subsequently p
