Diagnostic criteria for the study of chemical and physical processes by twin-electrode thin-layer electrochemistry

The application of twin working electrode thin-layer electrochemistry to interpretation of various chemical, electrochemical, and physical processes is discussed. It is noted that certain unique features of the thin-layer techniques are of particular advantage in the study of rates of chemical reactions coupled to the electron-transfer step, the electron-transfer reaction itself, adsorption phenomena, and reactions involving production of solids and gases. Several potential and current excitations are described, and the typical cell responses are illustrated and analyzed for their diagnostic value.
