文摘
- •
Selective oxidation of CH3OH to CH2O over a Cu foil has been studied by in situ gas phase XPS.
- •
C1s and O1s spectra were used for identification of reagents and reaction products in a gas phase.
- •
Catalytic data (conversions and reaction products yields) calculated from XPS spectra are in a good agreement with QMS results.
- •
The possible reasons of the observed variations in reaction mechanism have been discussed.
