AB  - It has been shown that the adsorption of Bi3+ and Tl+ cations occurs on oxide layers of Au and Pt electrodes in acid solutions. The initial stages of oxide formation and reduction are inhibited. The effect increases with increasing cation concentration, but diminishes with increasing anion concentration. The adsorption of cations originates in their interaction with the dipoles of the oxide species on Au and Pt surface. A hydrophilic nature of oxidized surface also facilitates this adsorption. Cations apparently affect the state of adsorbed water and decrease the lateral repulsion of oxide species and the electric field in the double layer. This causes a retardation of the place-exchange mechanism, leading to a stabilization of oxides, ie, their more irreversible reduction.

AB  - The electrocrystallization of thin anodic films on metal electrodes continues
 provoke interest since the original work of Bewick et al. [1]. These
studies have been focused on the film formation on mercury [1--3] and
amalgam electrodes [4,5]. Perhaps the most exact information about layer
growth has been obtained for these systems. There is no data on this type
of film formation on foreign single crystal substrates. In this note we report
a study of the formation of thallium oxide monolayer on single crystal gold
electrodes with the (100), (110) and (111) orientations. It has been found
that this two-dimensional (2D) film formation is highly dependent on the
crystallographic orientation of gold surfaces.

AB  - An electrocatalytic method developed previously for the depolarization of the hydrogen evolution reaction (HER) on graphite, iron, steel, nickel and titanium substrate surfaces was employed to improve the polarization characteristics of gold. The combination of two d metals from two branches of Balandin's "volcano" curve for the HER creates a marked electrocatalytic effect, particularly for molybdenum and cobalt which are added in situ as their anionic or complex species during the electrolytic process. The alloy activity appears to be shifted to potential values that are representative of precious metals and even exceeds these values at higher current densities; the shift is more than 700 mV over the current density range important for similar industrial applications. The synergetic electrocatalytic effects and the improvements in the polarization are illustrated by linear potential sweep voltammograms and steady state Tafel lines. The duration (the lifetime) of the electrocatalytic coating was about 4 months with simple reactivation by means of the in situ addition of negligible amounts of cheap and available cobalt and molybdenum species.
