Abstract

Anion adsorption from sulfuric acid solutions on a Pt(111) electrode was investigated with in-situ STM and cyclic voltarametry. An ordered (2 11 2) adlattice is observed in the potential range between 0.5 and 0.7 V. This adlattice is attributed to specifically adsorbed anions and interpreted as a coadsorbate of sulfate anions and water. Similarities as well as differences to anion adsorption on Rh(111) and Au(111) are discussed.
