Abstract:
Coadsorption of chlorine and oxygen on the Ag(111) surface has been studied with low-temperature scanning tunneling microscopy in combination with density functional theory calculations. Room-temperature adsorption of chlorine onto the Ag(111)-p(4 × 4)–O surface leads to the appearance of new bright objects located between protrusions of the 4 × 4 reconstruction. As chlorine adsorbs, objects form “rosettes” around corner holes. This configuration coincides with the configuration of the chlorine atoms in the Ag(111)-(3 × 3)–Cl reconstruction structure. We conclude that the adsorption of chlorine on the Ag(111)-p(4 × 4)–O surface occurs dissociatively, with chlorine atoms displacing oxygen atoms from the 4-fold positions. Adsorption of chlorine at 77 K results in the formation of the mixed Cl–O species on the Ag6 triangles of the p(4 × 4) reconstruction. Both scenarios of chlorine adsorption are unexpected and cannot be explained within a commonly accepted Ag6 model of the p(4 × 4) reconstruction.
