Communication demonstrates precise control of pressure in DRIFTS systems, highlighting adsorption behaviors on catalysts.
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.
