Abstract

A new X-ray absorption cell dedicated to in situ and operando experiments in heterogeneous catalysis has been built and tested. It allows measurement of X-ray absorption spectroscopy (XAS) spectra in transmission mode under the flow of various gas mixtures at elevated temperatures (600°C) and pressures (50 bar). The working conditions are representative of phenomena that take place in fixed bed reactors.
