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

Abstract

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.

 

Biography

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.
