Abstract
Bromine adlayers formed by flame annealing of platinum single crystal surfaces and quenching in bromine vapor were studied by STM and cyclovoltammetry. Bromine forms protective layers which, similar to iodine, prevent contamination of the surface and lead to well-defined surfaces. On Pt(111) a (4 × 4) structure is observed, on Pt(100) a disordered structure, both of which are compatible with densely packed adlayers of bromine. On the Pt(110) surface a complex structure is observed which is similar to that formed by iodine on Pt(110). The reconstructions of Pt(100) and (110) are lifted. Cyclovoltammetric peaks can be attributed to concomitant hydrogen adsorption and bromine desorption; the cyclovoltammograms in bromide electrolyte for clean and for bromine-quenched Pt(111) are identical.
