Abstract Developing efficient, low‐cost electrocatalysts for industrial‐level hydrogen production remains a significant challenge. Here lattice‐distorted Ni nanoparticles (NPs) encapsulated within nitrogen‐doped carbon shell on delignified wood (Ni‐NC@DWC) are constructed through chitosan‐induced assembly and the pyrolysis process. Experimental theoretical results indicate that lattice distortion due to strong metal‐support interactions, boosts electron transfer reaction intermediate adsorption/desorption, enhancing both urea oxidation (UOR) evolution (HER). Interestingly, active center 3+ ‐O is dynamically cyclically generated during UOR. When utilized as self‐standing electrode in an alkaline electrolyte, Ni‐NC@DWC exhibits low potentials of 24 mV 1.244 V at 100 mA cm −2 HER UOR, respectively. Moreover, achieves ultrasmall cell voltage 1.13 urea‐assisted water splitting can operate stably over 1000 h. Furthermore, when it self‐assembled anion exchange membrane (AEM) electrolyzer, requires only 1.62 2000 industrial operates 150 h without degradation, confirming highly attractive economical, sustainable, scalable production.
