Abstract

The total charge densities for stepped electrodes in solutions H2SO4 with an excess of an inert electrolyte is analyzed by the thermodynamics polarized electrode. Gibbs excess and the Gibbs energy of adsorption decrease with increasing step density or decreasing terrace length and indicates that adsorption of (bi) sulfate is stronger at larger (111) terraces.
