“…The measurements were carried out at the "Structural Materials Science" end-station installed at the Kurchatov synchrotron radiation source. 32,33 The X-ray diffraction patterns were measured in a transmission geometry (Debye-Scherrer) using Fujifilm phosphor imaging plates coated with a storage layer as an area detector. The X-ray beam size was 200×200 µm 2 , the wavelength λ = 0.68886 Å, the sample-to-detector distance was 150 mm, and the exposure time was 15 min.…”

The new phase, where peroxo groups are incorporated into titania particles, along with anatase and hydrated η-TiO 2 with peroxo groups on the surface of titania nanoparticles, were prepared by introduction of H 2 O 2 into reaction mixtures while synthesizing TiO 2 from TiOSO 4 or by cold impregnation of pre-synthesized TiO 2 . The samples were studied by a complex of methods (classical and synchrotron-radiation X-ray powder diffraction, small-angle X-ray scattering, high-resolution scanning electron microscopy with energy-dispersive X-ray spectroscopy, X-ray absorption spectroscopy, IR and Raman spectroscopy, X-ray photoelectron spectroscopy, UV-vis diffuse reflectance and absorption spectroscopy, DSC). The [TiO x (O 2 ) 2-x (H 2 O) m ] phase was first structurally characterized and compared to η-TiO 2 . Most samples of H 2 O 2 -sensitized TiO 2 discolor methyl orange under visible light irradiation faster than commercial Hombikat UV100 treated with H 2 O 2 . The activity of the samples strongly relating to their phase composition was associated with existence of large amount of titanium peroxo complexes along with formation of mixed-phase samples.

Abstract. The reductive decomposition of the complex Pd 2 Eu 2 (μ,η 2 -OOCMe) 2 (μ-OOCMe) 8 (H 2 O) 2 ·(HOOCMe) 2 upon heating from room temperature to 500°C in a hydrogen atmosphere was investigated by in situ synchrotron radiation-based X-ray absorption fine structure spectroscopy (XAFS) including observations of X-ray near-edge structure (XANES) and extended absorption fine structure (EXAFS) at Pd K-and Eu L 3 -edges and synchrotron X-ray diffraction (XRD). The Pd-Eu 2 O 3 nanocomposite was found to be the final thermolysis

“…A study of titanium dioxide samples using X-ray absorption spectroscopy (XANES/EXAFS) near the Ti K-edge was performed using synchrotron radiation at the Structural Materials Science beamline [36,37] of the Kurchatov Synchrotron Radiation Source (NRC "Kurchatov Institute", Moscow). For monochromatization of the beam, a Si (111) channel-cut monochromator was used.…”
