Abstract
In this paper, chemical environment of Fe/0.5 mol . dm(-3) H2SO4 system was designed according to the potentiostatic current oscillations mechanism ba sed on the temporal formation of Fe(OH)(2) and Fe3O4 films. The formation o f Fe(OH)2 and Fe3O4 films were promoted or inhibited through changing the p H and Fe2+ concentration in the interface of Fe/electrolyte. Thus the envir onment was created in that the current oscillations were observed. The resu lts provide support to the potentiostatic current oscillations mechanism of Fe/0.5 mol dm(-3) H2SO4 system based on the temporal formation of Fe(OH)2 and Fe3O4 films.
