Diamond electrodes possess unique chemical stability, a very wide potential window of water stability, and low background currents. These properties give rise to numerous possible applications, for example, electrosynthesis and electrodestruction reactions at extreme potentials and environmental conditions and as a sensor electrode in aggressive environments. Furthermore, the study of semiconducting diamond electrodes promises to lead to greater understanding of the surface chemistry of diamond and of electronic levels and surface states in doped diamond. In this paper the reactivity of diamond electrodes and their use in a molten salt environment, as a sensor element, and for characterizing diamond are discussed.
