Effect of platinum dispersion on the catalytic activity of Pt/Al2O3 for the oxidation of carbon monoxide and propene

- Pt/Al2O3 shows steady TOF of CO oxidation in the entire Pt dispersion range.
- TOF of C3H6 oxidation on Pt/Al2O3 strongly depends on Pt dispersion.
- Acrylate species participates as an intermediate in C3H6 oxidation on Pt/Al2O3.
- Reactivity of acrylate species on Pt/Al2O3 is different depending on Pt dispersion.
