Adsorption of SO2 on Pd(100) Studied by S K-Edge XAFS
Surface structure and an electronic property of SO2 adsorbed on Pd(100) were studied by S K-edge NEXAFS, SEXAFS and Sls XPS. The molecule was found by the polar-angle dependent NEXAFS to adsorb with the molecular plane normal to the Pd(100) surface. This is a clear contrast to the S02/Ni(100) case where the molecule lies flat on the surface. From the peak position of XPS and the x* peak height ...
متن کاملAdsorption and Surface Reaction of SO2 on Cu(100) Studied by S K-Edge XAFS and STM
Adsolption and reaction of SO2 on Cu(100) at room temperature has been studied by means of S K-edge XAFS, AES, LEED, XPS and STM. It has been revealed that there are atomic S and SO3 with the stoichiometric ratio of 1:2 on the surface. This indicates that a disproportionation reaction of 3SOz(a)+S(a)+2S03(a) occurs at room temperature. The atomic S locates in the fourfold hollow site. SO3 adsor...
متن کاملElectronic structure effects on B K-edge XANES of minerals.
In order to assess the usability of X-ray absorption near-edge structure (XANES) for studying the structure of BO(n)-containing materials, the dependence of theoretical XANES at the B K-edge on the way the scattering potential is constructed is investigated. Real-space multiple-scattering calculations are performed for self-consistent and non-self-consistent potentials and for different ways of...

متن کاملPhosphorus K-edge XANES spectroscopy of mineral standards
Phosphorus K-edge X-ray absorption near-edge structure (XANES) spectroscopy was performed on phosphate mineral specimens including (a) twelve specimens from the apatite group covering a range of compositional variation and crystallinity; (b) six non-apatite calcium-rich phosphate minerals; (c) 15 aluminium-rich phosphate minerals; (d) ten phosphate minerals rich in either reduced iron or mangan...
