- Oxidation of propylene on the Pt(111) surface in both UHV and 0.02 torr of oxygen begins with oxydehydrogenation of the vinyl hydrogen yielding a C3H5 oxidation intermediate.
- In the presence of oxygen pressures, propylene oxidation proceeds similarly to UHV conditions.
- Spectroscopic identification of the intermediate indicates it is an adsorbed tri-s 1-methylvinyl, before further skeletal oxidation.
- In pressures of both reactants, a C3H4 intermediate is formed, which is most likely propyne.
