Abstract Electrocatalytic oxidation of biomass‐derived 5‐hydroxymethylfurfural (HMF) presents a promising pathway for synthesizing the value‐added chemical, 2,5‐furandicarboxylic acid (FDCA). However, it is still lack scalable strategies to fabricate electrocatalysts with high activity and selectivity. Herein, bayberry‐like Ni@Ni 3 S 2 core–shell catalyst prepared via spontaneous corrosion strategy HMF electro‐oxidation. The Ni shells abundant electron‐deficient sites facilitate generation high‐valence 3+ OOH active species. Additionally, in situ 2− SO 4 enhances electron proton transport capacity. Both high‐performance liquid chromatography (HPLC) density functional theory (DFT) analyses reveal that preferentially selects 2,5‐dicarboxyfurylfuran (DFF) due lower reaction energy barrier from DFF, rate‐determining step DFF generate 5‐formylfuran‐2‐carboxylic (FFCA) significantly accelerated. Consequently, yield FDCA Faraday efficiency are found be 99.20% 99.35%, respectively, they reach 88.79% 90.33% after ten cycles, showing excellent stability. Moreover, mass production 13.97 g successfully synthesized using strategy. This work offers valuable reference designing catalysts by manipulating routes achieve efficient biomass conversion.
