Abstract
The promoting effects in the ethylene epoxidation reaction on an electrolytic silver surface by chemical modification with Ba and Cs compounds were studied. Ba increases the conversion of ethylene and decreases a little of the selectivity to ethylene oxide. In contrast, Cs increases the selectivity to EO at the expense of conversion of ethylene. Changes in the work function and the TPD of oxygen adsorption on modified Ag surfaces were measured. Promoting effects are explained by the idea that atomic oxygen is the crucial species for epoxidation.
