In Situ and Multi-frequency EPR for FeNC Materials and Model Complex (B07)

• Subject Area: Physical Chemistry of Solids and Surfaces, Material Characterisation
• Term: since 2022
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 443703006

Iron catalysis frequently involves paramagnetic states as crucial reaction intermediates. These states are accessible to electron paramagnetic resonance (EPR) spectroscopy. Herein, EPR is employed for the assignment and characterization of paramagnetic states in iron-nitrogen-carbon (FeNC) catalysts, FeN4 macrocycles and iron doped carbon materials. Development and application of advanced multi-frequency and in situ EPR methods will provide new insight into catalytic mechanisms involving paramagnetic states as well as Fe active site electronic and atomic structures.
