- Аннотация: A new atomically smooth renewable electrode is prepared and studied. The electrode is a liquid Pb-Ga alloy containing 0.06 atoms % of Pb. Its double layer characteristics differ drastically from those of a Ga electrode; they are practically identical to the characteristics of a Pb electrode. Thus, the Pb-Ga electrode actually is a model of the electrochemical properties of liquid Pb electrode. The adsorption of anions on the Pb-Ga electrode increases in the sequence BF4-=SO42-<Cl- <Br-<I-. In the absence of metal-solvent chemisorption interaction and at a fixed charge, the ’metal’ capacitance of the Pb-Ga electrode has an intermediate value between the ’metal’ capacitances of Ga and Hg electrodes; it practically does not depend on the solvent nature. In relation to water, propylene carbonate and formamide, the Pb-Ga electrode is much less lyophilic than the Ga electrode; its lyophilic nature is practically similar to that of the Hg electrode. For In-Ga, Cd-Ga and Pb-Ga electrodes possessing nearly the same electrochemical work function value, the solvent-chemisorption potential drop is shown to differ significantly; it increases in the sequence Pb-Ga<In-Ga<Cd-Ga, as the distance of the nearest approach of solvent molecules to the ion cores of the metal decreases. © 2002 Published by Elsevier Science B.V.
