Modulation Excitation Spectroscopy in Heterogeneous Catalysis

February 9 from 10:00 am11:00 am

Zoom Webinar with Juan J Bravo-Suárez
Center for Environmentally Beneficial Catalysis
Department of Chemical & Petroleum Engineering
The University of Kansas – Lawrence


We will discuss advances in our group in the development of tools and methods for modulation excitation spectroscopy (MES) for in situ characterization of heterogeneous catalysts. We will present a general overview of the technique including operation, requirements, advantages, limitations, and discrimination of surface reactive and spectator species. Additionally, we will also discuss MES evolution from jump and stop-flow transient and frequency response methods to the understanding of active sites and elementary steps kinetics, and future opportunities including the study of deactivating catalysts and microkinetics.



Dr. Bravo-Suárez received his Ph.D. in Chemical Engineering from Industrial University of Santander, Colombia (in collaboration with VPI&SU and S. Ted Oyama). He worked at AIST (Japan), UC-Berkeley, KU, and ADM Co. before joining KU as a faculty. He is the recipient of JSPS Postdoctoral Fellowship, ACS-PRF Doctoral New Investigator (2017) and NSF’s CAREER (2019) award. His main interests are the application of kinetics and in situ/operando spectroscopic methods for understanding and developing catalysts for chemical conversion and environmental applications.
