Abstract Inhibiting the deactivation of nickel‐based catalysts caused by self‐oxidation and competitive adsorption behavior is still a major challenge for urea oxidation reaction (UOR), especially under industrial‐level current densities. In this study, crystalline NiSe 2 /amorphous NiFe‐LDH (NiSe /NiFe‐LDH) heterojunction catalyst rationally constructed selective electrocatalytic UOR. situ Raman spectra ex characterization results reveal that such structure can tailor impede accumulation NiOOH species during UOR process. Density function theory simulations disclose self‐driven charge transport from electron‐deficient region to electron‐rich would induce formation local electrophilic/nucleophilic adsorb electron‐donating ‐NH electron‐withdrawing C = O groups, respectively. This optimizes molecules hinders overaccumulation OH − ions on surface /NiFe‐LDH, which beneficial priority occurrence over oxygen evolution (OER) realization high selectivity. Benefiting tailored favorable adsorption, /NiFe‐LDH could act as high‐selective anode achieve ultrahigh 800 mAcm −2 only at 1.447 V. Besides, UV–vis spectrophotometry also unveiled has capability electrochemically degrade urea, offering great promise practical application potentials.

Developing highly efficient biomass-derived carbon-based electrocatalysts remains challenging for urea electrolysis because most of these show powder morphology, which can lead to Ostwald ripening during the reaction process, and its mechanism should be further verified. Herein, self-supported lignin-derived carbon coupling NiO@MoNi
