Abstract
Specific adsorption of halogenides and silver halogenide phase formation was investigated by the combination of electrochemical quartz microbalance measurements (EQMB), topographical in-situ scanning force microscopy (SFM), and in-situ lateral force microscopy (LFM). In-situ LFM can be employed to monitor specific adsorption and, more generally, chemical conversion reactions in submonolayers of atomic species which are inaccessible to topological imaging by SFM. Reorganization of the electrochemical double layer during specific adsorption caused nanotribological changes. Hydrated anions in the outer Helmholtz plain are not locally bonded to a specific site and give low LFM friction values. Specifically adsorbed anions and ion pairs, on the other hand, impede the lateral cantilever translation, resulting in increased friction. EQMB measurements yielded data corresponding to the formation of up to one monolayer of specifically adsorbed cation−halogenide ion pairs. Anodic dissolution of silver to AgO- and th...
