Tip‐Encapsulated FeNi 3 in Wood‐Derived N‐Doped CNTs Arrays for Efficient and Stable AEM Seawater Electrolysis

, and a record solar-to-hydrogen (STH) conversion efficiency of 19.6%. This strategy advances AEMSE toward practical implementation by coupling the tip effect with wood-derived structural engineering, thereby achieving high activity, selectivity, and long-term operational stability.
