February 2012The figure shows typical cyclic voltammograms of single crystalline platinum electrodes in contact with an aqueous electrolyte (black) and with the oxygen ion conductor yttria-stabilized zirconia (red). The platinum at the interfaces gets oxidized and reduced during the measurement. In case of the aqueous electrolyte in addition the underpotential deposition of hydrogen and the evolution of oxygen are depicted.
