It is now clear that the local coordaintion of a „Single-Atom„ strongly affects its catalystic properties. In this talk, I will discuss examples from our recent work utilizing Fe3O4, Fe2O3, and TiO2 model supports, where the structure is precisely known and the local geometry can be determined [1]. Using a combination of atomcally resolved imaging, spectroscopy, and theoretical computations, I will show how the adsorption behavior of reactants can be understood by analogy to coordination complexes utilized in homogeneous catalysis [2]. Finally, I will utilize time-lapse STM movies to show how metal adatoms can be both stabilized and destabilized by adsorption of reactants and other molecules in a reactive environment [3] .
