Abstract Electrochemical biomass conversion offers a promising approach for organic synthesis and upgrading. Iron‐based catalyst hold considerable promise in this domain, however, challenges related to stability under electrocatalytic conditions limit their broader application. In work, an iron‐based integrated foam (FeO x /Fe‐IF) electrode fabricated via thermal treatment process is presented, which generates highly active stable mixed oxide species situ. The structural composition enables FeO /Fe‐IF exhibit outstanding activity 5‐hydroxymethylfurfural (5‐HMF) electroreduction, achieving near‐complete with high selectivity toward 2,5‐dihydroxymethylfuran (DHMF). Remarkably, maintains durability 5‐HMF approaching 100% DHMF around 92% over ten successive cycles. situ spectroscopic analyses reveal that Fe 2 O 3 effectively stabilize 4 sites, ensuring sustained catalytic performance. kinetic isotope studies suggest electrochemical hydrogenation (ECH) mechanism, where adsorbed hydrogen (*H) (*HMF) interact produce DHMF. Additionally, the demonstrates adaptability across broad pH range (7–14), efficiency continuous flow‐cell synthesis, great hydrogenating other biomass‐derived chemicals, underscoring versatility of /Fe‐IF. This work provides valuable insights designing efficient electrocatalysts conversion.
