“…CAMD's storage ring was operated at an energy of 1.3 GeV with electron currents between 200 and 80 mA. The synchrotron radiation was monochromatized by a modified Lemonnier-type monochromator (Lemonnier et al, 1978) equipped with InSb (111) crystals. The monochromatic flux rate per second on the sample was about 5610 8 photons (at 100 mA).…”

“…XANES spectra were collected at the XMP (X-Ray Microprobe) beamline at the Center for Microstructures and Devices (CAMD). For the XANES spectra, monochromatic light was obtained by using a double crystal monochromator of Lemonnier type [21], equipped with Si(311) crystal pair (d = 3.276 Å) and the overall resolution was 0.8-1.0 eV.…”

MoO 3 was dispersed onto mesoporous SBA-15 by using ammonium heptamolybdate as MoO 3 source. The formation of MoO 3 was carried out by heating the loaded material to 500°C for 3 h in air. Below 13 wt% Mo loading, no reflections of MoO 3 occur in the X-ray powder patterns and even for high MoO 3 contents, the intensities of the reflections are much lower than expected for fully crystalline material. A detailed XAFS analysis reveals that at low Mo contents, the metastable hexagonal modification of MoO 3 is formed despite the high calcination temperature of 500°C. It is highly likely that the nanosize of the particles and the interaction between MoO 3 and SBA-15 stabilize the metastable modification of the material. Nitrogen physisorption experiments show the typical type-IV isotherms indicating that the mesoporosity of the materials is preserved despite the large amount of MoO 3 .Transmission electron micrographs demonstrate the presence of MoO 3 inside the SBA-15 support. The Raman spectra display a remarkable size-dependent intensity loss and several features give evidences for a bond formation between nano-sized MoO 3 particles and the silica support. Moreover, the spectroscopic details suggest the formation of (MoO 3 ) n oligomers.
