Nuclear forward scattering (NFS) is a synchrotron-based technique relying on the recoil-free nuclear resonance effect similar to Mössbauer spectroscopy. In this work, we introduce NFS for and measurements during electrocatalytic reactions. The technique enables faster data acquisition and better discrimination of certain iron sites in comparison to Mössbauer spectroscopy.

- Iron shows promise as a non-toxic energy carrier for long-term energy storage, but detailed knowledge of its oxidation kinetics for micrometer-sized particles is limited.
- This study uses temperature-programmed oxidation and boron nitride dilution to prevent sintering, allowing investigation of individual particle behavior during oxidation.
- Findings reveal that iron oxidation follows a parabolic rate law, with key data on phase compositions and rate constants obtained, emphasizing the importance of particle size distribution in modeling oxidation kinetics.
The design of a (57)Fe Synchrotron Mössbauer Source (SMS) for energy-domain Mössbauer spectroscopy using synchrotron radiation at the Nuclear Resonance beamline (ID18) at the European Synchrotron Radiation Facility is described. The SMS is based on a nuclear resonant monochromator employing pure nuclear reflections of an iron borate ((57)FeBO(3)) crystal. The source provides (57)Fe resonant radiation at 14.
