Electrodeposition of iron(II) on platinum in chloride melts at 700-750 °C

The electrodeposition of iron(II) on platinum electrodes in chloride melts was studied by cyclic voltammetry. The process is irreversible and is complicated by platinum-iron alloy formation. The deposition is accompanied by iron dendrite formation. Thereby, after achieving a steady state for iron deposition on platinum in the melt, the Pt surface was covered by up to 40% atom iron only. The electrochemical parameters of this process were determined. A plausible mechanism scheme was proposed.
