The replacement of the thermodynamically unfavorable anodic oxygen evolution reaction (OER) with a more favorable organic oxidation reaction, such as benzylamine, has garnered significant interest in hybrid water electrolyzer cells. This approach promises production value-added chemicals alongside hydrogen fuel generation, improving overall energy efficiency. However, achieving high current density for benzylamine without interference from OER remains challenge, limiting practical efficiency cell. In this study, we investigated room temperature method sulfur introduction VNi-layered double hydroxide (LDH) catalyst and its application electrocatalytic oxidation. S-introduction VNi-LDH was found to modulate electronic states nickel vanadium, increasing number active sites, electrochemical surface area, charge transfer properties. resulting S-VNi-LDH achieved 400 mA cm–2 at only 1.39 V vs RHE potential oxidation, avoiding evolution. demonstrated 100% selectivity (Faradaic Efficiency = 98.6%) conversion into benzonitrile within 2.5 h reaction. two-electrode electrolysis system, cell voltage 1.50 when substituted showed consumption 4.67 kWh/m3 H2 1.31 during indicating exceptional stability over five cycles, maintaining 98.6 ± 0.4% FE consistent voltage. also oxidized various amines, including benzylamines secondary (95–97%) faradaic (85.8–98%). study presents an eco-friendly, room-temperature S-doping VNi-LDH, which out performed reported catalysts literature.

3d–2p–5d Orbital Synergy in Electrocatalytic Hydrazine Oxidation Assisted Water Splitting with Industrial Scale Current Density

Inorganic Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: March 2, 2025

The hydrazine oxidation reaction (HzOR) is a promising alternative to the oxygen evolution (OER) in electrolyzers due its lower potential than water, which significantly reduces energy demands and enhances hydrogen production efficiency. Incorporating high-valent 5d metals into 3d metal hydroxides has shown great for enhancing water-splitting performance through strong 3d–2p–5d orbital interactions, improving charge transfer, intermediate adsorption, reducing overpotentials. This study showcases an innovative approach enhance electrocatalytic of Co(OH)2 incorporation metal, tungsten (W6+), using straightforward electrochemical synthesis method. W6+ led significant Co3d–O2p–W5d coupling, strengthening electronic interactions between Co W. facilitated electron withdrawal from Co2+, promoting easier access Co3+ sites catalytic performance. W-Co(OH)2 achieved current density 100 mA cm–2 at 1.00 V versus RHE HzOR, notably 1.54 required OER. In two-electrode system, substituting OER with HzOR resulted reduction cell voltage by 0.50 V.
