Operando Hard X-ray Spectroscopy
Synchrotron radiation facilities are powerful X-ray sources that can be employed for numerous experimental techniques, such X-ray spectroscopies, scattering and imaging. Unique features of synchrotron radiation - high intensity and broad energy spectrum - make these sources ideally suited for in-situ and operando investigations of advanced materials. In the focus of our group research is the application and development of complimentary synchrotron radiation techniques (X-ray absorption spectroscopy, high-energy X-ray diffraction coupled with pair distribution function analysis, small-angle X-ray scattering) that provide information about the transformations of catalyst structure on different length scales under catalytically relevant conditions. By combining unique synthesis methods, state-of-the art tools for experimental characterization and advanced approaches to data analysis, atomistic details of chemical and electrochemical reactions at gas/solid and liquid/solid interfaces are revealed, and structure-properties relationship in these materials are established.
