Electrochemical oxidation synthesis of energetic compound coupled with energy-efficient hydrogen evolution

Electrocatalytic water splitting process involves hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), where OER is a high energy-consumption step. Electro-oxidation of small molecules instead of OER and coupled with HER is a potential strategy for changing this situation. This work describes a coupling system for synthesizing energetic compounds (EMs) and hydrogen production using a ruthenium-doped nickel diselenide catalyst on carbon fiber paper (CFP@NiSe2@Ru). The coupling system was established to combine 3,4diaminofurozan (DAF) oxidation with overall water splitting (OWS). It was achieved to an ultra-low cell voltage of 1.30 V at 10 mA cm(-2) for 3,3 '-diamino-4,4 '-azofurazan (DAAF) green synthesis and hydrogen production simultaneously. This work established a new path towards the energy-efficient generation of H(2 )and the green electrosynthesis of DAAF.
