Abstract:
WS 2 nanosheets hold great promise for a variety of applications yet faces a grand challenge in terms of large‐scale synthesis. We report a reliable, scalable, and high‐yield ( 〉 93 %) synthetic strategy to fabricate WS 2 nanosheets, which exhibit highly desirable electrocatalytic properties toward both the alkaline sulfion (S 2− ) oxidation reaction (SOR) and the acidic hydrogen evolution reaction (HER). The findings prompted us to develop a hybrid alkali‐acid electrochemical cell with the WS 2 nanosheets as bifunctional electrode catalysts of alkaline anodic SOR and acidic cathodic HER. The proof‐of‐concept device holds promise for self‐power or low‐electricity electrolytic H 2 generation and environmentally friendly recycling of sulfion with enhanced electron utilization efficiency.
