Fermi energy guided topochemical reaction strategies for electrocatalytically active Ba-rich transition metal oxyfluorides, oxyhydroxides and their combination (A05)

Subject Area Solid State and Surface Chemistry, Material Synthesis
Physical Chemistry of Solids and Surfaces, Material Characterisation
Term since 2023
Project identifier Deutsche Forschungsgemeinschaft (DFG) - Project number 463184206
 
Project A05 is focused on the preparation of mixed anion compounds for the oxygen reduction reaction in electrocatalytic applications. Here, Ba-rich perovskite compounds of the system BaTi1−x−yFexCoyO3− are targeted. These compounds are capable for many anion exchange reactions, which can alter the Fermi energy and charge transition levels in various ways. Concepts of subsequent and simultaneous synthesis strategies for multinary anion compounds such as oxide hydroxide fluorides are considered. The influence of the electronic structure on both, the catalytic properties as well as on strategies for synthesis is analyzed experimentally and theoretically in collaboration with the other projects.
