Coadsorption of sodium and water on MgO„100.../Mo„100... studied by ultraviolet photoelectron and metastable impact electron spectroscopies

چکیده
The coadsorption of D2O and Na on the MgO~100!/Mo~100! surface has been studied by metastable impact electron spectroscopy and ultraviolet photoelectron spectroscopy ~He I!. The initial layer of D2O adsorbed on the MgO~100! surface at 100 K ‘‘wets’’ the surface. For multilayer adsorption, the outermost water molecules exhibit an electronic structure which is very similar to gas phase water. Na dosed onto a D2Oprecovered MgO surface leads to the formation of a hydroxide species, most likely NaOH. This hydroxide species is stable to 530 K. © 1998 American Vacuum Society. @S0734-2101~98!06103-X#

Interaction of methanol and water on MgO„100... studied by ultraviolet photoelectron and metastable impact electron spectroscopies
The coadsorption of methanol (CH3OH) and water (D2O) on the MgO~100!/Mo~100! surface at 100 K has been studied by metastable impact electron spectroscopy ~MIES!, ultraviolet photoelectron spectroscopy @UPS ~HeI!#, and by thermal programmed desorption ~TPD!. Methanol wets the MgO surface and adsorbs nondissociatively within the first monolayer with the hydroxyl group oriented toward the substrat...
متن کاملAdsorption of benzene on Mo(100) and MgO(100)/Mo(100) studied by ultraviolet photoelectron and metastable impact electron spectroscopies
By employing metastable impact electron spectroscopy (MIES) and ultraviolet photoelectron spectroscopy (UPS) together with work-function measurements, three adsorption states of benzene have been identified on the clean Mo(100) surface at 100 K: a chemisorbed layer, a second physisorbed layer with the aromatic rings plane parallel to the surface, and at higher coverages, an adsorbed layer with ...
متن کاملCharacterization of surface defects on MgO thin films by ultraviolet photoelectron and metastable impact electron spectroscopies
Metastable impact electron spectroscopy ~MIES! and ultraviolet photoelectron spectroscopy are used in this study to investigate low-defect and defective MgO~100! thin films. Unlike low-defect films, defective films exhibit a new spectroscopic feature located ;2 eV above the top of valence band. Exposing the defective film to oxygen quenches the emission of electrons from F centers created on th...

MgO films ~2 nm thick! were grown on Mo and W substrates while metastable impact electron ~MIES! and ultraviolet photoelectron spectroscopy ~UPS! ~HeI! spectra were collected in situ. Apart from the valence band emission no additional spectral features have been detected with electron spectroscopies. After exposing the oxide surface to Mg ~substrate temperature between 100 and 300 K! an additio...
متن کاملMg clusters on MgO surfaces: characterization by MIES and electronic structure ab initio calculations
MgO ®lms (2 nm thick) were grown on Mo and W substrates while metastable impact electron (MIES) and photoelectron spectra (UPS(HeI)) were collected in situ. Apart from the valence band (VB) emission no additional spectral features have been detected with electron spectroscopies. After exposing the oxide surface to Mg (substrate temperature between 100 K and RT) an additional peak, not seen with...
