The mechanism of the CH4/O2 reaction on the Pd-Pt/γ-Al2O3 catalyst: A SSITKA study

- Lattice oxygen is exchanged with gas phase oxygen.
- Lattice oxygen and chemisorbed from the gas phase takes part in methane oxidation.
- Two different kinds of active centres are presented on the catalyst surface.
- Methane oxidation proceeds simultaneously by two different reaction mechanisms.
