Applied Spectroscopy, Materials and Catalysis
The research in the Susanne Mossin Group is focused on the use of advanced spectroscopic techniques to investigate the structure, reactivity, and mechanisms of catalysts, coordination compounds, and bioinorganic molecules. Central to the group’s work are in-situ and operando spectroscopy, including EPR spectroscopy, as well as dynamic nuclear polarization (DNP) NMR for probing reaction intermediates. The overarching aim is to gain fundamental insight into catalytic processes, electronic and magnetic structures, and oxygen activation in both heterogeneous and homogeneous systems.
Research
Current activities span deNOx catalysis, NO oxidation, O₂ activation, and the study of catalytic mechanisms in transition-metal-based systems. A particular focus is placed on copper zeolite materials, where in-situ EPR has been applied to elucidate their reactivity. DNP NMR is employed to follow intermediates in homogeneous catalysis, while electronic and magnetic structure determination supports the design of new functional materials.
Key contributions in our group include the conceptualization of a consistent reaction scheme for the NH₃-SCR reaction, the discovery and characterization of a novel iron(III) compound — a single-molecule magnet with spin-crossover behavior — as well as the elucidation of the correlation between magnetic anisotropy and structure in manganese(III) compounds. Together, these studies advance the understanding of structure–function relationships in catalysis and inorganic chemistry.
