Resolving transient responses in catalyst systems using MES-DRIFTS in a low-volume reaction chamber
The Reece Lab, part of the Rowland Institute, Havard University, has been developing novel methods for catalyst characterisation using spectroscopic tools. A detailed understanding of the reaction kinetics for solid-gas heterogeneous catalysis aids the design of future catalyst systems for efficient chemical production and energy production. Modulation excitation spectroscopy (MES) combined with Diffuse Reflectance Infrared Fourier Transform spectroscopy (DRIFTS) is a technique that has potential to uncover insights into the transient responses of catalyst systems.

Active site titration for CO oxidation catalyzed by Pt/SiO2 using Pulse-Probe DRIFTS
Well controlled gas pulsing experiments at reaction temperatures under intermediate pressures on supported catalysts can provide an avenue for bridging the detailed understanding from surface science model systems to the design of real-world catalyst systems. Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS) was employed on a supported catalyst to investigate the evolution of surface-bound intermediates using CO oxidation as a probe reaction.
