Electrochemical N-N Oxidatively Coupled Dehydrogenation of 3,5-Diamino-1<i>H</i>-1,2,4-triazole for Value-Added Chemicals and Bipolar Hydrogen Production.

ABSTRACT: Electrochemical H₂ production from water favors low-voltage molecular oxidation to replace the oxygen evolution reaction as an energy-saving and value-added approach. However, there exists a mismatch between the high demand for H₂ and slow anodic reactions, restricting practical applications of such hybrid systems. Here, we propose a bipolar H₂ production approach, with anodic H₂ generation from the N-N oxidatively coupled dehydrogenation (OCD) of 3,5-diamino-1H-1,2,4-triazole (DAT), in addition to the cathodic H₂ generation. The system requires relatively low oxidation potentials of 0.872 and 1.108 V vs RHE to reach 10 and 500 mA cm^-2, respectively. The bipolar H₂ production in an H-type electrolyzer requi
