Bipolar electrochemistry
WebJun 4, 2024 · Bipolar electrochemistry (BPE) refers to an electrochemical phenomenon that wirelessly induces an asymmetric polarization and redox reactions on a conductive or semiconductive object, i.e. bipolar electrode (BE), in the existence of a sufficient electric field between two conductive feeding electrodes. Bipolar electrochemistry is a phenomenon in electrochemistry based on the polarization of conducting objects in electric fields. Indeed, this polarization generates a potential difference between the two extremities of the substrate that is equal to the electric field value multiplied by the size of the … See more When an electrically conductive electrode placed without a direct connection, in the same electrolyte, between an anode and cathode in an electrochemical cell with sufficient voltage being applied; the electrode will … See more The phenomenon of bipolar electrochemistry is known since the 1970s and is used in industry in some electrolytic reactors.
