Abstract
The coadsorption of water with bromine on Cu(110) and Cu(111) has been studied using UPS, LEED, TDS and δφ. The results show that water is more strongly bound to the surface in the vicinity of the bromine than on the clean substrate. This behaviour is interpreted as surface hydration of the partially ionic bromine.Information about the dipole orientation of the solvation water is derived from the observed δφ-values. The LEED studies indicate that island formation with long-range order of the mixed bromine-water layer occurs at fairly low bromine coverages. The experimental results are qualitatively similar on the close-packed (111) and the more open (110) surfac. The relevance of these findings to the electrochemical phenomenon of specific anion adsorption on metal electrodes is briefly discussed.
