The stability and the conversion of atomically dispersed Pt2+ species to sub-nanometer Pt particles have been investigated as a function of the Sn concentration in Pt–CeO2 films by means of synchrotron radiation photoelectron spectroscopy, resonant

We have conducted resonant angle-resolved photoemission spectroscopy of well-defined ${\mathrm{CeO}}_{2}$(111) and $c--{\mathrm{Ce}}_{2}{\mathrm{O}}_{3}$(111) model surfaces, revealing distinct $f$ contributions in the valence band of the two compoun

Thin films of reduced ceria supported on metals are often applied as substrates in model studies of the chemical reactivity of ceria based catalysts. Of special interest are the properties of oxygen vacancies in ceria. However, thin films of ceria pr
