Abstract

Abstract: Paired electrochemical reactions allow the optimization of both atom and energy economy of oxidation and reduction reactions. While many paired electrochemical reactions take advantage of perfectly matched reactions at the anode and cathode, this matching of substrates is not necessary. In constant current electrolysis, the potential at both electrodes adjusts to the substrates in solution. In principle, any oxidation reaction can be paired with any reduction reaction. Various oxidation reactions conducted on the anodic side of the electrolysis were paired with the generation and use of hydrogen gas at the cathode, showing the generality of the anodic process in a paired electrolysis and how the auxiliary reaction required for the oxidation could be used to generate a substrate for a non‐electrolysis reaction. This is combined with variations on the cathodic side of the electrolysis to complete the picture and illustrate how oxidation and reduction reactions can be combined. Abstract : Many paired electrochemical reactions use perfectly matched reactions at the anode and cathode, but this matching is not necessary. In constant current electrolysis, the potential at both electrodes adjusts to the substrates in solution. Oxidation reactions were paired with H2 generation, showing the generality of the anodic process. This effort was followed by pairing multiple cathodic reactions with a pair of established oxidation reactions.
