Zusammenfassung:DRIFTing through time: Modulation excitation in situ diffuse‐reflectance IR Fourier transform (DRIFT) spectroscopy with periodic isotopic perturbation (D2 and 13CO) has been applied to elucidate the pathway for the preferential oxidation of carbon monoxide (PROX) over a commercial Pt/alumina catalyst. The time‐ and phase‐domain IR spectra suggest a water‐assisted pathway for the preferential oxidation reaction.
