Two-dimensional electrocrystallization of thallium oxide on the single crystal gold surfaces

Abstract

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.
