Oxygen adsorption on gold in potassium hydroxide solution
Abstract
The adsorption of oxygen-containing particles from potassium hydroxide solutions weres studied
at polycrystalline gold electrode. Five stable forms of oxygen has been determined as adsorption
− − ads Au OH , ads Au −O&H , ads Au −O&& and phase AuO and Au2O3. Stationary adsorption of
components are described by Temkin’s isotherm. The kinetics follows Roginski-Zeldovich equation.
Adsorption Ox,Red-transformations of oxygen in
Au,O&H | OH −; Au,O&& | OH − and Au OH O, & | &&systems are quasi-equilibrium.
