Abstract

The methods of temperature-programed desorption and temperature-programed reaction spectroscopy are used to show that ethylene glycol is reversibly adsorbed on a nonoxidized silver surface with the formation of multilayer coating. The character of the interaction of ethylene glycol with an oxidized silver surface depends on the strength of the oxygen-catalyst bond and the temperature of ethylene glycol adsorption. The form of ethylene glycol weakly adsorbed on the silver surface is responsible for the selective formation of glyoxal via two parallel mechanisms - dehydrogenation and oxidation. The dissociative interaction of ethylene glycol with the silver surface yields formaldehyde and carbon dioxide as by-products.
