Figure 4. (A) CO-DRIFTS spectra for catalysts with different Rh wt.% contents; (B) NO conversion for different catalysts under dry and (C) wet conditions; (D) NH₃ production; (E) NO conversion, and CO₂ production for the series of catalysts (1000 ppm NO, 5,000 ppm CO, 2% H₂O when used); (F) Schematic of product formation during NO reduction over catalysts with different Rh structures^[91].
