Seminar

Preparation of Model-Catalysts for Fundamental Studies in UHV

In this seminar, I will summarize surface science studies addressing transition metal oxide surfaces that have been conducted at the iNANO center in Aarhus. Although we often start our studies with high-resolution scanning tunneling microscopy (STM), it is the combination of STM studies with various other techniques, such as X-ray photoelectron spectroscopy (XPS), and infrared reflection absorption spectroscopy (IRRAS), and density functional theory (DFT) calculations, which leads to a knowledge gain. Firstly, I will present examples found on the anatase TiO2(101) surface (a-TiO2). The interaction with vanadium, the preparation of V2O5/ a-TiO2 and WO3/ a-TiO2 model catalysts will be addressed, as well as the interaction of water with a-TiO2(101). If time permits, I will summarize our results addressing ultrathin FeO islands supported on Pt(111). After assigning of the islands edges at oxidizing and reducing conditions, I will discuss an in-situ STM experiment of the CO oxidation reaction.
