Title: In-situ Catalyst Characterization at Stanford Synchrotron Radiation Lightsource (SSRL): What’s New?

Abstract: In-situ catalyst characterization is fundamental to understanding the structure of the active catalyst. Synchrotron X-ray techniques are powerful methods for such characterization. As such, X-ray absorption spectroscopy (XAS) has been the dominant synchrotron method, and for good reason. At Stanford Synchrotron Radiation Lightsource (SSRL) we have begun a program to transform the capabilities at the facility to provide a range of capabilities for in-situ catalyst characterization. These new capabilities allow new experiments to be performed, and new information and new understanding to be gained.  This talk will highlight some of these capabilities that have been implemented, or are under development at SSRL. Topics to be covered include: (i) The ability for high-pressure operations (up to 70 bar) for diffraction and spectroscopy. (ii) The capability to study long-term deactivation phenomena in e.g. Fischer-Tropsch catalysts, (iii) the methodology to study single atom catalysts using HERFD and EXAFS analysis, and (iv) The development to quick-scanning and continuous scanning XAFS to study ligand exchange kinetics in supported molecular catalysts.
