Abstract

In this chapter the experimental results on adsorption of bromide ion on Pt(100) surface is described.

According to DFT calculations, Monte Carlo simulations, and CV and STM measurements in 0.1 M HClO4 + 10−2 M KBr solution, H+ and Br co-adsorb at 0.19 V (RHE) and adsorb/compete for the same surface sites. The surface is always saturated, but the ratio H/Br changes with potential. Br forms a c(2 × 2) structure on terraces. At step sites the same process occurs already at 0.15 V (RHE) [1, 2, 3, 4].
