Correlative and Multi-Modal Quasi In Situ and Operando Spectroscopy and Microscopy (B06)

• Subject Area: Physical Chemistry of Solids and Surfaces, Material Characterisation
• Term: since 2018
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 388390466

Project B06 studies the effect of frustrated phase transitions to the catalytic performance of spinel and perovskite catalysts in liquid-phase oxidation reactions. The microscopic catalyst structure as well as the electronic and geometric properties of the working structure under catalytic conditions are studied by state-of-the-art electron microscopy, X-ray and electron paramagnetic resonance spectroscopies, alongside X-ray microscopy for multi-modal correlative quasi in situ and operando studies. These methods allow for monitoring function-determining properties, including the surface morphology, crystal structure and local structure, the electronic structure and oxidation/spin states of active transition metal sites, as well as oxygen vacancies and radical reaction pathways during alcohol and hydrocarbon oxidation reactions over Co-based spinels and perovskites.
