Capillary-assisted bipolar electrochemistry: a focused minireview

L. Bouffier, N. Sojic, A. Kuhn

Electrophoresis, 2017, in press

A bipolar electrode is quite unconventional as it behaves simultaneously as an anode and a cathode in contrast to a classic electrochemical setup where the electron-transfer reactions are promoted on two different electrodes. The driving force is the polarization potential established between the solution and the bipolar electrode which allows a wireless electrochemical addressing. In the past decade or so, bipolar electrochemistry (BPE) has encountered a remarkable renewal of interest with extraordinary potentialities ranging from materials science to analytical chemistry. For practical reasons, BPE experiments are very often performed in home-made electrochemical cells comprising tubes or capillaries. This review is focussed on specific applications based on such types of experimental set-ups, from the macroscale where the tube acts only as an ordinary container down to the microscale where specific properties of the capillary come also into play.
