Comparative Investigation of Electrocatalytic Oxidation of Cyclohexene by Proton-Exchange Membrane and Anion-Exchange Membrane Electrolyzers

Abstract Electrocatalytic oxidation of cyclohexene was performed in proton-exchange membrane (PEM) and anion-exchange membrane (AEM) electrolyzers. For the efficient electrocatalytic oxidation, the anode catalyst material, applied potential, and solvent used were optimized. In addition, the differences in reactivity between the PEM and AEM electrolyzers were clarified and a mechanism for the oxidation of cyclohexene in each electrolyzer was proposed.
