Kurzfassung englisch:
Iron oxides have been used as support materials in some of the most influential papers on single atom catalysis, and remain a popular choice due to their low cost and high stability. In the literature, the FeOx catalysts are often modelled as hematite (α-Fe2O3), specifically the (0001) facet. However, this surface remains poorly understood: The most commonly observed termination in experiment is a superstructure with unknown atomic configuration, and stabilizing any monophase surface appears to be challenging. Adatom adsorption has not been experimentally investigated in any detail. I will discuss both the (0001) facet and the less investigated (11 ̅02) surface, which exposes either a simple bulk-truncated termination or a reduced (2 × 1) reconstruction. I will present experimental results on the stabilization of adatoms on the (11 ̅02) surface and discuss the suitability of the two facets as model systems.
