摘要：
The adsorption and decomposition of ethylene oxide(EtO)on Cl-modified and oxygen-pre-covered Ag(111)at low temperatures with high resolution electron energy loss spectroscopy(HREELS)arestudied.At 140 K,EtO is molecularly adsorbed on the surface.At above 230K.with atomic oxygen on thesurface,a small amount of EtO decomposes into ethylene and is oxidized to produce some oxidation productsas water,etc.while with dioxygen on the surface,a large amount of EtO decomposes into ethylene and isoxidized to produce large amounts of oxidation products like water and so on.The experimental resultsshowed that chlorine can,on the one hand,decrease the adsorption amount of EtO and,on the other hand,inhibit the further oxidation of EtO.
