Recent advances in the understanding of electrocatalysis and its relation to surface chemistryIt is pointed out that electrosorption plays a key role in electrocatalysis. Little information is available, however, concerning the chemical nature of the interactions of the adsorbed species with the electrode and even less about the adsorption sites. The role of adsorbed species and surface layers in electrocatalysis is reviewed for several electrode systems. In recent years, some general insights have been achieved into the relationship of hydrogen electrode kinetics to hydrogen adsorption. For a given mechanism the exchange current density is related to the standard free energy of adsorption of the particular type of adsorbed hydrogen upon which the kinetics depend. The oxygen electrode reactions are less well understood than the reactions for the hydrogen electrode. The pronounced irreversibility of the oxygen electrode reactions at moderate temperatures has severely complicated mechanistic studies.
