Looking into the reactor: Operando infrared spectroscopy for studies of reaction mechanisms in heterogeneous catalysis

COLLINS, SEBASTIAN

Conferencia; 4th Catalysis Meeting of Regional 2; 2021

Understanding the reaction mechanism and the relationship between architecture of the active sites and their reactivity in heterogeneous catalysts allows the design of new and optimized materials. In our group we develop in situ and operando (under realistic conditions of reaction) techniques to selectively identify reaction intermediaries and to propose reaction pathways. With this aim, we design, model/optimize and build spectroscopic micro-reactors, using multidisciplinary tools. Special techniques using time-resolved spectroscopy (TRS) and modulation excitation spectroscopy (MES) experiments will be presented. Examples using these techniques will be discussed for liquid and gas phase systems.
