Figure 3. FTIR differential spectra of CO adsorption on the Pt/Sn-Al2O3 sample after pulse propane and reaction completion. After each pulse experiment, the sample was cooled to 30 °C, and the spectrum was collected after adsorption and desorption of CO. The temperature was raised to 600 °C for the next propane pulse experiment. The CO adsorption FTIR spectra of periods 1-2 and 9-10 were collected. FTIR: Fourier transform infrared spectroscopy.
