The role of defects, or active states, in surface electrochemistry with particular reference to gold in neutral solution Burke, L, O'Connell, A and O'Mullane, A 2003, 'The role of defects, or active states, in surface electrochemistry with particular reference to gold in neutral solution', Journal of Applied Electrochemistry, vol. 33, pp. 1125-1125.

The role of such states at gold surfaces in neutral aqueous media (an important electrode system in the microsensor area) was explored using cyclic voltammetry. It was demonstrated that, as postulated in earlier work from this laboratory, there is a close relationship between premonolayer oxidation, multilayer hydrous oxide reduction and electrocatalytic behaviour in the case of this and other metal electrode systems. Some of the most active, and therefore most important, entities at surfaces (e.g., metal adatoms) are not readily imageable or detectable by high resolution surface microscopy techniques. Cyclic voltammetry, however, provides significant, though not highly specific, information about such species. The main conclusion is that further practical and theoretical work on active states of metal surfaces is highly desirable as their behaviour is not simple and is of major importance in many electrocatalytic processes.
