Abstract:
Reactivity of oxygen states absorbed at the surface of a silver foil towards ethylene has been studied by XPS, TPD and TPR. Isotope experiments with “ionic” oxygen (BE9(C 1s)=528.4 eV) labelled by 18O2 and the “covalent” oxygen (BE(O 1s)= 530.5 eV) labelled by 16O2 have been carried out. It has been revealed that both oxygen states are desorbed separately. Following the ethylene experiment indicated that the “ionic” oxygen is active in total oxidation only, while the “covalent” oxygen takes part in the ethylene epoxidation.
