In a comprehensive spectroscopic study we will evaluate the electronic structure and chemical speciation of iron in various surroundings. Well-defined Fe model systems will be prepared and characterized regarding their electronic, morphological, and chemical properties. With photoemission and X-ray absorption spectroscopies, the influence of the chemical surrounding on Fe‘s electronic configuration will be determined, enabling strategies to tune its redox behavior. Aim is to generalize these findings to control Fe‘s reactivity in collaboration with theoretical and other experimental projects.
