| Summary: | Due to their diverse properties and functionalities, cost-effective transition metal-based nanomaterials have been rigorously studied for electrochemical applications. Ultrathin nanosheets have been identified as the most effective electrodes for catalyzing water-splitting reactions in both acidic and alkaline environments. Here, we reported ZnWO<sub>4</sub>, a member of the tungstate family, as an effective electrocatalyst for promoting the electrochemical hydrogen evolution reaction. The Zn<sup>+2</sup>-stabilized tungstate showed a remarkable cathodic reaction during the water-splitting reaction with low overpotential (136 mV at 10 mA cm<sup>−2</sup>) and small HER kinetics (Tafel Slope = 75.3 mV dec<sup>−1</sup>) and long-term cyclic durability. The high-valence tungsten stabilized with divalent Zn<sup>+2</sup> promotes electron transfer during the reaction, making it an advanced electrocatalyst for green hydrogen production. |
