ADSORPTION AND SURFACE REACTIONS OF H[SUB]2 S AND SO[SUB]2 ON CU(100) STUDIED BY ELECTRON ENERGY LOSS SPECTROSCOPY

摘要: The adsorption of H{sub 2}S and SO{sub 2} on Cu(100) was investigated by use electron energy loss spectroscopy as a function coverage, temperature, scattering angles. In particular, irreversible dissociation the formation sulfhydryl (SH) species at low immediate coverage were observed temperature. This followed molecular physiadsorption higher coverage. case Cu(100), decomposition 3} surface room temperature observed. A reaction involving preadsorbed with 2}s is discussed.
