Seawater electrolysis has emerged as a promising solution for decarbonizing the global energy sector, but challenges like anode corrosion and high catalyst costs have impeded progress. To overcome these obstacles, a team of researchers from China and Australia developed an innovative approach. By introducing tungsten into NiFe-based catalysts and utilizing wood-based carbon structures as a substrate, they created the W-NiFeS/WC electrode. This electrode exhibited a three-dimensional hierarchical porous structure with excellent conductivity, enhancing its efficiency in seawater electrolysis. The electrode's rich redox-active centers and electrocatalytic properties enabled superior performance in both oxygen and hydrogen evolution reactions. The electrode's low cost and high effectiveness present a compelling option for sustainable hydrogen production from seawater. Furthermore, this research highlights the importance of structure reconstruction in energy conversion reactions and demonstrates the potential of repurposing wood waste into efficient catalysts, embodying a circular economy approach for green hydrogen production.
