I3C solid-state NMR spectroscopy has been used to study the various species formed during the oxidation of ethylene on Ag catalysts. The NMR spectra obtained after heat treatments of sealed catalyst samples provide direct observation of surface species which can be identified by their chemical shift values. This study also reports I3C shifts for standard compounds dispersed on Ag/q-A1203 and Ag/SiOz which provide groups that can be ...
