The Implications of Coupling an Electron Transfer Mediated Oxidation with a Proton Coupled Electron Transfer Reduction in Hybrid Water Electrolysis

Abstract

AbstractInvited for this month′s cover are the groups of Menny Shalom at the Ben‐Gurion University of the Negev, Israel and Dr. Biswajit Mondal at Indian Institute of Technology Gandhinagar, India. The image shows the connection between two half‐cells: an electron transfer‐mediated [(2,2,6,6‐tetramethyl‐1‐piperidin‐1‐yl)oxyl] (TEMPO)‐catalyzed benzylamine oxidation at the anode and a proton‐coupled electron transfer at the cathode for hydrogen generation. The difference in pH dependence of the anodic and cathodic processes enables hybrid water electrolysis at low cell potential (∼1.0 V) by adjusting only the pH value of the electrolytic medium.
