Overlimiting current by iodide electrode oxidation in aqueous media: an electrogenerated iodine interphase with positively charged channels stimulating in situ electrokinetic iodide transport

Overlimiting current by I − electrode oxidation on a Pt ultramicroelectrode in an aqueous solution was investigated, which was attributed to the formation of a positively charged porous iodine interphase in situ stimulating electrokinetic I − transport.
