Adsorption of oxygen on copper and silver

Oxygen adsorption on silver has been studied using field-emission microscopy. It has been shown that adsorption is an activated process which proceeds on rough planes through the stage of formation of adsorption islands, O_ads. Using a semi-empirical interacting bonds method, the heat of oxygen adsorption has been estimated in a dissociative from on the (111), (100) and (201) planes of silver and on the (111) and (100) planes of copper.
