Using precise gas exposures to resolve surface site filling in diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS)

Year: 2025

Type: article

Abstract: In this communication we report how to assemble a DRIFTS system that can precisely control the pressure in the cell from < 10-6 Torr to atmospheric pressure using easily accessible components. As a proof-of-principle we adsorb and react CO over a Pd/Al2O3 catalyst where we can observe pressure, temperature, and reaction-dependent preferential binding to adsorption sites.
