The utilization of anion exchange membrane (AEM) electrolyzers presents an opportunity for commercial production 2,5-furandicarboxylic acid (FDCA) through electrochemical oxidation 5-hydroxymethylfurfural (HMF). Consequently, developing facile synthesis techniques scaled-up electrocatalysts HMF reaction (HMFOR) is a crucial step. Herein, we developed one-step soaking method preparing 100 cm2 NiCu-based catalyst on Ni foam (NiCuOx/NF) in 10 s. In single-pass 25 AEM electrolyzer assembled by the obtained catalyst, high yield ≥95.0% and selectivity ≥99.9% were achieved to produce FDCA continuously with 200 mM electrolyte. After h stable operation at A, 207.28 g was attained purity over 99%. This work provides valuable insights into industrial-scale commercialization biomass upgrading electrolyzers.
