“…Further, the worldwide hydrogen energy demand was ∼59 Mt in 2010 and surpassed 74 Mt in the year 2020. It is estimated that this demand may go up to 211–528 Mt in the next 2–3 decades, which can generate USD ∼3 trillion in revenue by 2050 through hydrogen value chains. − Thus, one of the key pillars of sustainable development is the efficient production of hydrogen and oxygen under moderate reaction conditions.…”

The use of sustainable and green hydrogen fuel has received significant attention in recent years, and their production via water splitting technology is sternly hindered by the thermodynamically unfavorable anodic reaction. Herein, orthorhombic CoV 2 O 6 •2H 2 O nanosheets (NSs) were obtained by a facile sonochemical method (328 K, 1 h), and their performance toward the oxygen evolution reaction (OER) is reported for the first time. The hierarchical sheetlike structures render the significant electrochemical active surface area and lowest charge transfer resistance in the alkaline medium (KOH) constituting ethylene glycol (EG). The CoV 2 O 6 •2H 2 O NSs modified nickel foam (CoV 2 O 6 •2H 2 O NSs/NF) unveils an overpotential of 340, 360, and 400 mV at the high current densities of 100, 200, and 500 mA cm −2 , respectively, at the optimized content of EG (∼10 mmol). The electrolyzer functioning with CoV 2 O 6 •2H 2 O NSs/ NF and KOH solution of EG can reduce electrical energy consumption by ∼11.5% and thereby suppress the hydrogen production cost accompanied by the generation of value-added products. The present investigation spotlights the combined effects of lowtemperature synthesis, hierarchical structures, and presence of EG to promote the OER kinetics.

“…Clean hydrogen stands out as the ideal solution to address the severe global crises associated with energy and environmental pollution . With its distinctive attributes of high energy density, pollution-free combustion, and sustainable supply, hydrogen is considered a potential replacement for conventional fossil energy resources . Despite these advantages, the current industrial method of hydrogen production heavily relies on fossil fuels, thereby exacerbating CO 2 emissions. , Consequently, significant efforts are underway to explore cleaner, more sustainable, and energy-efficient methods of hydrogen production .…”

Alkaline water electrolysis has the potential to become an important method for producing green hydrogen and achieving net-zero carbon emissions. Consequently, the development of catalysts with higher catalytic values for the hydrogen evolution reaction (HER) is essential for advancing the water-splitting technology. This study introduces a facile deposition strategy using aerosol-assisted chemical vapor deposition to fabricate a bimetallic RuCo alloy on nickel foam (NF), which serves as a Pt-free, high-performance HER catalyst under alkaline conditions. The synergy between Co and Ru, along with the structural advantages of RuCo@NF, significantly enhances the electrocatalytic performance. The optimized RuCo@NF catalyst exhibited HER activity, achieving current densities of 10 and 100 mA cm–2 at low overpotentials of 17 and 100 mV, respectively. Moreover, it had a minimal Tafel slope of 42 mV dec–1 and demonstrated stability over 24 h, surpassing that of the benchmark Pt/C catalyst when measured in 1.0 M KOH. Furthermore, density functional theory analysis validated the experimental results, revealing a lower Gibbs free energy value for the RuCo alloy (−0.35 eV) compared to that of metallic Ru (−0.50 eV) and Co (−0.57 eV) in the HER process. This study presents a convenient pathway for the development of a highly active and robust bimetallic thin-film electrocatalyst, demonstrating its potential for hydrogen production in fuel cells.
