Abstract:Nuclear forward scattering (NFS) is a synchrotronbased technique relying on the recoil-free nuclear resonance effect similar to Mossbauer spectroscopy. In this work, we introduce NFS for in situ and operando measurements during electrocatalytic reactions. The technique enables faster data acquisition and better discrimination of certain iron sites in comparison to Mossbauer spectroscopy. It is directly accessible at various synchrotrons to a broad community of researchers and is applicable to multiple metal is… Show more
