Cyclic voltammetry at gold single-crystal surfaces .2. Behaviour of high-index faces

Typical cyclic voltammograms at high-index faces of gold in acidic electrolytes are given and discussed comparatively. These findings may be considered as a starting point for further electrochemical studies on these faces; they provide a basis for comparison of results obtained on different samples of the same nominal crystallographic orientation in the same laboratory or in different laboratories. They can also be compared instructively with cyclic voltammograms for the same processes at low-index faces (Part 1, J. Electroanal. Chem., 407 (1996) 1.). The implications of the results for elucidating potential-induced surface reconstruction are also considred.
