A new, inexpensive transmission-IR cell capable of transient isotope and operando experiments is demonstrated. Operando-IR characterization of Au/TiO2 and Au/Al2O3 shows that WGS rates correlate with CO adsorbed on Au0. SSITKA on Au/TiO2 and Au/Al2O3 shows that molar fraction of surface active intermediates is 0.41 mol.%Au and 0.1 mol.%Au, respectively.
