abstract = {The atomic structure of surface layers and the local
changes of surface morphology during the initial stages of
anodic oxidation of Ag(111) in an aqueous 0.1 M NaOH
solution have been investigated by in situ scanning
tunneling microscopy (STM) under different polarization
conditions. The surface oxide formation starts at
underpotentials, i.e. at electrode potentials E below the
Nernst-potential E-3DAg2O (vs. SHE) = 0.4 V for the
formation of the three-dimensional (3D) bulk Ag2O phase. An
ordered overlayer showing distinct Moire pattern is observed
in the potential range -0.1 V < E (vs. SHE) < 0.1 V. The
appearance of the Moire structure is assigned to the strong
OH adsorption, which induces a stretching of the 2D lattice
of the OH-terminated topmost Ag(111) monolayer. In situ STM
imaging at higher potentials (0.1 V < E (vs. SHE) < 0.3 V)
shows the occurrence of a Ag dissolution process followed by
an underpotential oxide formation in agreement with previous
electrochemical measurements and in situ X-ray absorption
studies. (C) 2003 Elsevier B.V. All rights reserved.},
