Iron, upgraded!

Iron will be explored in three different environments, oxidic, (pseudo-)molecular and metallic, to identify the respective inherent properties. We use magnetism, different spectroscopies and catalytic reactions to probe and understand the influence of the environment. This broad perspective coupled with an overarching interpretation allows us to draw application-specific and general conclusions. We envision that this approach enables a future use of iron in a broad variety of applications where iron and its compounds will take over diverse roles and functions: as catalyst, redox or structural promotor, in magnetic or functional materials. To elucidate the interplay of redox properties, selectivity, reactivity and stability, the use of specific and precise analytical methods is mandatory. We will therefore apply and further develop unique and coupled in situ/operando methods and new theoretical approaches.

The aim to upgrade iron is a timely and relevant topic. Several chemical processes and materials are based on rare, expensive, toxic or environmentally harmful metals such as ruthenium, platinum, palladium or lead. There is an urgent demand for innovative and sustainable materials and processes. For example, cheap catalysts are required for the oxygen reduction reaction in fuel cells. Embedded in the right environment, iron is an ideal candidate for this task as well as for several other applications. The CRC Iron, upgraded! conducts basic research as a foundation to realise this vision.
