Au adsorption via the ionization of adsorbed hydrogen takes place in two steps. The first step is the formation of Aubulk, then the Auads is formed via the ionization of Aubulk. One adsorbed Au atom occupies 1.25 hydrogen adsorption sites, whilst at low coverages this value rises to 2.5. The Pt covered with Auads shows a catalytic effect on the oxidation of Cl- ions. The Auads does not desorb in Cl--free media.
