1. Observing phase changes in real time on ultrathin Iron oxide surfaces
University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenAbstract : Studying catalysts under such non-equilibrium conditions is a step towards approaching more realistic reaction conditions for working catalysts. Reactivity during phase changes of ultra-thin FeO2 films grown on Pt(111) are studied in situ with Ambient Pressure X-ray Photo Emission Spectroscopy and Quadrupole Mass Spectrometry, while running the CO oxidation reaction at 160°C and 0:6 mbar.
