Fig. 1: Monitoring NxOy species in H-SSZ-13 with FTIR.
From: Biomimetic CO oxidation below −100 °C by a nitrate-containing metal-free microporous system
a In-situ FTIR NO stretching region during sequential NO2 adsorption (2 Torr) on H-SSZ-13 with Si/Al ~12. The b OH stretching region during the process is described in A. c Adsorption of excess NO2 (2 Torr) on NO2-saturated sample in A. IR cell vacuum was used as background (not zeolite itself) in a, b, and c.
