Electrocatalytic Self-Coupling of N-Heterocyclic Amides for Energy-Efficient Bipolar Hydrogen Production.

ABSTRACT: This study proposes a green electrochemical strategy for addressing the high-energy-barrier oxygen evolution reaction (OER) in traditional overall water splitting. Leveraging the thermodynamic advantages of N-H bond activation/cleavage and N-N coupling processes, the 3,5-diamino-1,2,4-triazole (DAT) oxidative coupling reaction (DATOR) has been introduced to replace the high-energy-barrier oxygen evolution reaction (OER). This substitution enables low-energy-consumption hydrogen production while simultaneously yielding high-value azo energetic materials. Furthermore, to enhance electron and atom economy, the anodic DATOR process allows the hydrogen radicals (H*) generated from amine dehydrogenation to chemically combine via the Tafel process, producing hydrogen gas.
