(479f) Applications of Synchrotron Techniques for in Situ Catalytic Studies
AIChE Annual Meeting
Wednesday, November 16, 2022 - 2:20pm to 2:42pm
The availability of tunable and intense photon sources from synchrotron allows investigations of thermocatalysis and electrocatalysis under reaction conditions. In particular, the X-ray absorption fine structure (XAFS) method provides a wealth of knowledge in characterizing the electronic, structural and compositional properties of catalysts. For example, for a particular element of interest, the near-edge region (XANES) contains information regarding its oxidation state, the extended region (EXAFS) allows the analysis of its local coordination environment, and the edge-height of the spectrum is related to its elemental concentration. In this talk we will provide several examples to demonstrate the capabilities of synchrotron techniques for in situ studies of both thermocatalysis and electrocatalysis. We will also provide information on how to receive assistance from the Synchrotron Catalysis Consortium (SCC).
