Abstract

It is demonstrated that via the catalytic disproportionation of Sn2+ ions an adsorbed tin layer can be formed on the Pt surface. The characteristics of this monolayer are similar to those formed from SnCl4 solution via the ionization of hydrogen adsorbed on Pt. It is proved that the desorbing tin, upon anodic polarization, dissolves in the form of Sn4+ ions. The site requirement of an adsorbed tin atom is S = 2.2 hydrogen adsorption sites and its electrosorption valency is γ = 3.6.
