Crystal face effects on adsorption of ionic and non-ionic species on Ag electrodes: an electrochemical and STM study

The behaviour of the low-index faces of silver towards specific adsorption from aqueous solutions was investigated by measuring the adsorption of n-hexanol and tert-pentanol, which exemplifies the behaviour of physisorbed neutral compounds, the adsorption of bromide ions, which exemplifies the behav...

Description
Summary:The behaviour of the low-index faces of silver towards specific adsorption from aqueous solutions was investigated by measuring the adsorption of n-hexanol and tert-pentanol, which exemplifies the behaviour of physisorbed neutral compounds, the adsorption of bromide ions, which exemplifies the behaviour of chemisorbed ions, and the adsorption of uracil. STM images of specifically adsorbed bromide and iodide ions on Ag(111) were determined. The increase in the adsorptivity of the two aliphatic alcohols in the order Ag(110)
