Abstract
FeOOH deposition films were formed on gold electrodes by polarization in an electrolyte containing Fe2+. The time dependence of the formation current suggests a diffusion-controlled formation process. The oxidation of Fe(CN)64- at FeOOH films shows no Tafel-like behavior. It is assumed that the Fe2+ to form the film, as well as the Fe(CN)64- to be oxidized, have to diffuse through an adherent, strongly hydrous layer of Fe(OH)3 to the surface of FeOOH.
