Abstract Common precursors for carbon materials typically include petroleum‐based polymers or MOF materials. However, these often encounter challenges such as metal aggregation, high cost, and metals leaching. In this work, a novel of approach lignin‐metal supramolecular framework complex (MSF@Lignin) is introduced. These complexes are formed through oxidative ammonolysis lignin (OAL) to synthesize nitrogen‐doped carbon‐encapsulated CoRu nanocatalyst (CoRu@OALC) via in situ carbonization. CoRu@OALC exhibited exceptional performance both HER (90 mV) OER (200 at the current density 10 mA cm −2 , with an overall water splitting voltage 1.5 V outstanding stability under density. During pyrolysis process, became encapsulated by lignin‐derived carbon, occurring within temperature range 600–700 °C. catalytic active sites primarily located defects showcasing unique “self‐healing” phenomenon layer. Oxygen‐containing intermediates ( * OH, O, OOH) facilitated reconstruction on layer, while hydrogen‐containing H) contributed reappearance defect‐rich structure.
