Abstract

The covalent oxygen chemisorbed on silver has been characterised by XPS, UPS, TPD and TPR. It has been shown that this oxygen species active in ethylene epoxidation is characterised by full isotope scrambling in TPD spectra of O2 and the absence of UPS lines located below the silver 4d zone. Both the results testify its atomic origin.
