The Use of the Freece Technique for the Investigation of Electrochemical Behavior

Abstract

The background, experimental procedures and some results using the FREECE technique are described. Properties of liquid and frozen HC104*5.5H20 with respect to electrical conductivity and deuteron NMR are discussed. Electrochemical behavior of the metal-(liquid or frozen) electrolyte interface as observed in capacity measurements and charge transfer reactions is described. In the case of hydrogen evolution on copper, silver and gold, temperature dependent transfer coefficients are found. For copper and silver, straight Tafel lines with a slope of 85mV independent of temperature result in a transfer coefficient that is proportional to temperature. Some implications of the results for the understanding of electrochemical processes on a molecular level are discussed. The importance of UHV work on water-ion coadsorption on metal surfaces for the understanding of electrochemical processes on a molecular level is emphasized.
