Fig. 3: Monitoring CO oxidation with FTIR.
From: Biomimetic CO oxidation below −100 °C by a nitrate-containing metal-free microporous system
In-situ FTIR during an increase of temperature from 100 K (red line, described in Fig. 2a, H-SSZ-13 with Si/Al ~12) to 135 K. At this temperature CO2 starts to evolve and the temperature is held until CO2 reaches the maximum level (~2 min). The inset shows the magnified CO2 region. Note that we collected spectra at temperatures intermediate between 100 and 135 K, and no CO2 formation was detected until 135 K. Zeolite pellet itself was used as IR background.
