Effect of the irreversible adsorption of oxocarbons on the structure of bismuth adlayers on Pt(111) electrodes
The adsorption of organic residues on Bi-Pt(111) surfaces gives rise to a bismuth adsorption state different from that characterized by the redox couple at 0.62 V. After the stripping of organic adspecies, surface diffusion of bismuth adatoms takes place in order to attain their most stable distribution on the Pt(111) surface.
