    In situ time-resolved XAS study on metal-support-interaction-induced morphology change of PtO2 nanoparticles supported on γ-Al2O3 under H2 reduction
    Through in situ time-resolved X-ray absorption spectroscopy (XAS), we observed the dynamic behavior of the formation of two-dimensional low-coordinated Pt particles through reduction of PtOx particles by H2, which were under metal-support interaction (MSI) with the γ-Al2O3 support. The relatively st...

    Chapter 9. Catalysis XAS study of V2O5/Al2O3 catalysts doped with rare earth oxides
    This paper reports on XAS studies of well dispersed V2O5/Al2O3 and V2O5/Sm2O3/Al2O3 samples. XAS spectra at V-K and Sm-LIII edges show that the rare earth oxide favours the formation of regular tetrahedral units, [VO4], over the surface of the support. Positions of the preedge peak at the V-K edge, ...

    XAS study of Zn-doped Al2O3 after thermal treatment
    This study used synchrotron-based X-ray absorption spectroscopy (XAS) to investigate the electronic properties and coordination environment of zinc in the Zn-doped Al2O3 after thermal treatment at 500 and 1100 °C for 2 h. Zn XANES spectra show that there is a main peak at the edge between 9665 and 9...

    Does -Al 2 O 3 support reduce PTO 2 particle morphology?
    In summary, our in situ time-resolved XAS study on the reduction mechanism of PtO 2 particles over γ -Al 2 O 3 support observed the behavior of morphology change from three-dimensional PtO x particles to two-dimensional low-coordinated structure upon reduction of the interfacial PtO x species stabilized by γ -Al 2 O 3 surface.

    Is Almo 6 hPa a molybdate based catalyst?
    The striking conclusion is the dominant presence of AlMo 6 HPA and molybdate-based species in the CoMo/Al 2 O 3 catalyst and the Mo/Al 2 O 3 catalyst, respectively. It is noteworthy that such proportions are in agreement with the Raman discussion aforementioned. Table 2.

    Why is the XAFS signal smoothed at 20035 eV compared to Bulk MoS2?
    The slight smoothing of the structures above the main resonance located at 20035 eV compared to the bulk MoS 2 phase, and well evidenced in the EXAFS signal, arises from the formation of nanocrystalline MoS2 slabs.
