Key Ideas
- Professors from Chinese and Australian universities developed a method to improve the stability of NiFe-based electrodes in seawater electrolysis, enhancing hydrogen generation.
- The new approach involves incorporating tungsten into the NiFe-based catalysts, resulting in improved anti-corrosion properties and stability of the electrodes.
- The electrode's unique structure with W-NiFeS/WC composition showed superior performance in both oxygen and hydrogen evolution reactions in alkaline seawater.
- The study highlights the potential of using wood-based carbon structures for advanced electrochemical devices, promoting sustainable hydrogen production from seawater and embracing a circular economy approach.
Professors Hong Chen, Bing-Jie Ni, and Zongping Shao have developed a novel method to enhance the stability of NiFe-based electrodes in seawater electrolysis for sustainable hydrogen generation. By incorporating tungsten into the catalysts, they improved anti-corrosion properties and stability. The newly created WC-supported W-doped NiFe sulfide electrode exhibited a three-dimensional hierarchical porous structure with high conductivity and efficiency, outperforming standard catalysts in both oxygen and hydrogen evolution reactions. The study emphasizes the significance of wood-based carbon structures in developing efficient electrochemical devices and promotes a circular economy approach by recycling wood waste into catalysts for green hydrogen generation. This research not only contributes to more sustainable energy solutions but also addresses challenges in seawater electrolysis, paving the way for the adoption of eco-friendly hydrogen production methods.
