Figure 5.
Reaction network analysis and coverage distribution for different reactions on Pd/CeO2 at 100, 200, and 300 °C: (a) NO + CO reaction and (b) NO + CO + H2 reaction. Here, the dominated reaction pathways are marked in green and deep gray. The key intermediates for the dominated pathways (green) are displayed. Partial pressures of NO, CO, and H2 are 0.01, 0.01, and 0.005 atm, respectively. (c) Structures for the key intermediates (color code: gray, Ce; pink and red, O; black, C; blue, N; turquoise, Pd; white, H). The dashed circles represent surface oxygen vacancies.
