Abstract

Abstract A recently developed rotating bipolar electrode cell, equipped with wiper blades, is described as a continuous activator of the electrode surface; the thickness of the oxide film is easily controlled and at a particular potential the rate of processes occurring on the oxide film can be greatly increased. Furthermore, at a particular current density the reaction potential can be significantly altered, and the products of electrolysis changed. The oxygen evolution reaction and the competing Kolbe dimerization reactions, taking place at Pt in aqueous acid electrolyte, provide specific illustrations of the operating principles.
