Abstract

In this chapter the experimental results on adsorption of bromide ion on Pt(111) surface is described.

In 10 mM KClO4 (pH = 4) solution in the presence of 3 mMKBr, bromide adsorbs at 0.1 V (RHE). A structural transition is observed at 0.3 V (RHE), and (3 × 3)-Br (θBr = 0.444 ML) structures, an asymmetric and a hexagonal, seem to coexist randomly on the Pt(111) (1 × 1) surface. No clear transformation between them could be observed [1, 2, 3].

Xu et al. found two coexisting structures, (3 × 3) and (√3 × √3)R30°, at intermediate coverages [4].
