Oxide formation and anion adsorption have been studied on gold single crystal stepped surfaces. Most of the measurements were performed in sulphuric and some in perchloric acid solutions by cyclic voltammetry and by double layer capacity measurements. A pronounced structural sensitivity of both oxide formation and anion adsorption was found. The effects of the terrace orientation, step orientation and step density are reflected in voltammetry and the double layer capacity measurements. A systematic dependence of both processes on step density was found and their interrelation is discussed. The results contradict some gas-phase data reporting no critical role of steps in oxygen chemisorption on gold. A correlation between the relative surface energy of gold single crystals and the peak potentials of the initial stage of oxide formation was found.
