Abstract

In this chapter the experimental results on adsorption of sulfate ion on Au(110) surface is described.

CV and STM measurements, as well as “shell-isolated nanoparticle-enhanced Raman spectroscopy” studies in 0.1 M H2SO4, yielded no SO42−specific superstructure but a reversible reconstruction/deconstruction of the substrate surface. The clean and well-annealed Au(110) electrode exhibits intermixed (1 × 2) and (1 × 3) patches. Peaks at 0.090 V and 0.075 V (SCE) correspond to the electrochemical lifting/formation of the Au(110) reconstruction, with the unreconstructed surface at positive potentials and the reconstructed, increasingly corrugated, surface at negative potentials.

Above 1.050 V (SCE), the surface is oxidized and, in the reverse scan, in the range 0.650 V < E < 0.950 V reduced [1].
