Microwave activation of electrochemical processes at microelectrodes

Electrochemical experiments at platinum microdisc electrodes are shown to b e possible in an environment of intense microwave radiation and a considera ble current enhancement observed for the ferrocyanide/ferricyanide redox co uple in aqueous 1 M KCI is shown to be Faradaic in nature consistent with a rapid heating effect causing the temperature in the liquid phase at the el ectrode/solution interface to locally superheat.
