Silver single-crystal

Single crystal silver substrates have been used exclusively by Foresti et al. [115, 116, 123, 124]. They use macroscopic Ag single crystals, formed in house. They have formed a number of II-IV compounds using EC-ALE, including ZnSe, CdS, and ZnS. 

The underpotentlal deposition of lead has been examined on LEED-characterized single crystal silver surfaces with 0.1 M HF as the electrolyte using a special ultra-high vacuum-electrolyte transfer system. Each of the low index surfaces has a characteristic voltammetry curve with multiple adsorption and desorption UPD peaks. 

The authors acknowledge very helpful discussions with Dr. R. Adzic of the Institute of Electrochemistry, Belgrade, concerning the underpotential deposition of lead on single crystal silver substrates after chemical polishing. The authors also acknowledge support of the research by the U.S. Office of Naval Research.

The majority of studies aimed at understanding the mechanisms of ethylene epoxidation rely on either experimental physical chemistry studies of single crystal-silver surfaces or computational studies looking at enthalpies of different reaction states. One unfortunate caveat of the experimental studies lies in the fact that the binding of ethylene to the silver surface is too weak for ultrahigh vacuum (UHV) studies to be of any use. Therefore, the majority of silver surface epoxidation reactions use olefins that stick to the surface better both before and after epoxidation (e.g., butadiene or styrene). 

The synthesis of silver nanocubes by the reduction of Ag with glucose in the presence of CTAB has also been reported, see Figure 11.29 [85]. In this synthesis there is no separate seed preparation step. The Ag combines with the Bf of the CTAB to produce AgBr which maintains a low concentration of Ag in solution. During the reaction, single crystal silver seed nanoparticles are formed. The CTAB stabilizes the less stable 100 faces of these, as PVP does in the polyol process, and so nanocubes are the preferred final morphology.

Summary. We present a brief survey of methods that utilize computer simulations and quantum and statistical mechanics in the analysis of electrochemical systems. The methods, molecular dynamics and Monte Carlo simulations and quantum-mechanical density-functional theory, are illustrated with examples from simulations of lithium-battery charging and electrochemical adsorption of bromine on single-crystal silver electrodes.
