Abstract

Heterogeneous catalysts' properties are dependent on dynamic changes of the catalyst surface: modifications at the atomic level induce changes of the chemical properties. They may change their structure depending on the local reaction conditions. That is why it is crucial to have a better comprehension of the structure-function relationships via in situ and operando studies. With the venue of the 4th generation synchrotron source SIRIUS, new operando/in situ characterizations are developed for spatially and time-resolved investigations. To this end, a gas effluent analysis system, such as the mass spectrometer of this EMU project, will be implemented and combined to the synchrotron studies. (AU)
