Underpotential Deposition on Au Single Crystals

Cyclic voltammograms of Pb on low-index single-crystal Au were obsaved in HC104. Voltammograms of Pb underpotential deposition on various index Au faces were observed in 0.01 M HCIO4-1- ImM Pb solution. Since the voltammograms of Pb underpotential deposition are 

Atomically resolved STM images of underpotential deposition on Au(lOO) and Au(lll) in sulfuric acid solution were first observed by Magnussen et al. in 1990, features of which are shown in Figs. 19, 20, 

In situ STM images were observed in the cases of Zn underpotential deposition on Au(lll) with and without r in phosphate solutions/ Underpotential deposition of T1 on Au(lOO) and Au(ll 1) was investigated by X-ray scattering and STM in perchloric acid solution. Both measurements gave c(p x 2) monolayer structures before bulk deposi- 

Underpotential deposition of Zn on Au(lOO) inO.lM Na2S04was investigated by in situ XANES to obtain an indication of alloy formation.  

An in situ EUR study of bisulfate and sulfate adsorption indicated that the coverage of adsorbed sulfate increased in the presence of Cu underpotential deposition on polycrystalline Au.
