摘要: Abstract The adsorption of D2O on Ni(100) at 100 K in the presence and absence coadsorbates O(a), CO(a) D(a) has been investigated using thermal desorption spectroscopy, ultraviolet X-ray photoelectron work function change measurements. Adsorption is molecular, but some dissociation does occur heating extent depends strongly small coverages coadsorbates. Cluster formation island growth are not observed for D2O(a) alone surface. interactions between O(a) dependent oxidation Ni Low react with two to produce a new species stoichiometry 2 OD(a).D2O(a). tends inhibit decomposition D2O(a), evidence presented D2O-CO hydrogen bonding effects. High significantly weaken D2O(a)-Ni interactions. This increases tendency cluster as result enhanced relative importance bonding. Each three causes shifts valence levels lower binding energy Fermi level. These largely changes system. Shifts O(1s) level also observed, equivalent valence-level shifts.
