Abstract Electrochemical oxidation of 5‐hydroxymethylfurfural (HMFOR) to generate high‐value chemicals under mild conditions acts as an energy‐saving and sustainable strategy. However, it is still challenging develop electrocatalysts with high efficiency good durability. Here, nickel foam (NF) supported CoCrCe(7.5%)‐LDH (layered double hydroxides) by doping Ce into CoCr‐LDH show (HMF) conversion (99%), 2,5‐furandicarboxylic acid (FDCA) yield Faraday (100%) at 1.4 V RHE . The also exhibits remarkable stability 97% HMF after 10 cycles. X‐ray absorption near‐edge spectroscopy (XANES) theoretical calculation that beneficial the formation high‐valance Co significantly facilitates electron transfer, regulates adsorption behavior intermediates, reduces Gibbs free energy barrier accelerates reaction rate. This work promotes use rare earth elements promote HMF.

Published: Feb. 5, 2025

Abstract As a pivotal bio‐based building block, 2,5‐furandicarboxylic acid (FDCA) holds immense and broad application potential in the chemistry industry. Its polymeric derivative, polyethylene furandicarboxylate (PEF), emerges as an appealing alternative to conventional petroleum‐based terephthalate (PET). The electrochemical route for oxidizing 5‐hydroxymethylfurfural (HMF) into FDCA presents significant advantages over thermochemical processes, without requirements of high temperature, pressure, chemical oxidants, precious metal catalysts, featuring higher energy efficiency. Furthermore, electrosynthesis at anode can be synergistically integrated with selective reduction reactions cathode, enabling simultaneous production two desirable value‐added products further enhancing overall utilization This work reviews advancements electrocatalytic HMF (EHTF), encompassing catalyst design, reaction mechanisms, coupling strategies, reactor configurations. It also indicates challenges opportunities EHTF provides insights future development directions.
