Electrochemical water splitting is a promising approach in the development of renewable energy technologies, providing an alternative to fossil fuels. It has attracted considerable attention recent years. The benchmark materials used are precious metals that expensive and scarce. Therefore, this work proposes strategic electrochemical synthesis reduced graphene oxide cobalt-nickel hexacyanoferrate (rGO/CoNiHCF)-derived composite (rGO/CoNiPBd-OOH) achieve optimized OER performance. optimum rGO/CoNiHCF was fabricated with Co:Ni precursors 3:1 ratio ferricyanide solution pH = 1.0. Using alkaline treatment, well-distributed globular particles CoNiHCF over rGO sheets were converted into layered frameworks metallic (oxy)hydroxide species, giving final rGO/CoNiPBd-OOH nanocomposite. This nanocomposite presented favorable kinetic activity resulting Tafel slope 33 mV dec

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.
