    XPS study of the Al/Pd interface (1989)
    Chichester [u.a.] : Wiley-Blackwell
    Surface and Interface Analysis 14 (1989), S. 153-157

    Notes: The formation of the interface between a Pd polycrystalline substrate and Al deposits was followed by photoemission. Interdiffusion takes place readily and shows an evolution with time as well as under electron irradiation. The thickness of the mixed layer depends on the thickness of the Al deposit. The effect results in a narrowing of the Pd valence states.

    Characterization by XPS and XAS of supported Pt/TiO2—CeO2 catalysts (1990)

    Notes: TiO2 and CeO2 are will known for inducing strong metal-support interactions J(SMSI) of a different nature when used as supports for Pt catalysts. X-ray photoelectron spectroscopy analysis of mixtures of TiO2—CeO2 oxide supports (80:20 and 20:80) reveals at the surface a remarkable stabilization of cerium in the +3 oxidation state; the stabilization is more pronounced with lower cerium oxide concentration. X-ray absorption spectroscopy measurements done on the LIII edge show the same variation as a function of cerium oxide concentration, but in the bulk the reduction is much lower. Cerium in Pt/TiO2—CeO2 catalysts exhibits the same behaviour.
