Figure 8. (A) NO conversion and (B) N₂ and N₂O selectivity of CuFe-N/C, Cu-N/C, and Fe-N/C (1,000 ppm NO, 2,000 ppm CO, Ar balance, 30,000 h^-1). (C) Reaction pathway for NO reaction with CO on CuFe-N/C^[129]. Copyright 2021, American Chemical Society. The Fourier transform of extended X-ray absorption fine structure (EXAFS) spectra in the R face obtained from (D) Pd K-edge and (E) Pt L-edge adsorption spectra of Pt and Pd species; (F) HAADF-STEM image of Pt-Pd SAC-2. (G) NO conversion of Pt-Pd SAC-2, Pt SAC-2 and Pd SAC-2 (500 ppm NO, 10,000 ppm CO, 1,000 ppm C₃H₆, 1.25% O₂, He balance, 120 L g^-1 h^-1).
