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.

Green hydrogen production technology is an effective strategy for solving energy problems and environmental issues. In this paper, we report a bipolar system: Au–CuxO/CF∥Ru–CuxO/CF, in which the cathode produces through evolution reaction (HER) process anode formaldehyde oxidation (FOR). It found that when Au–CuxO/CF used FOR, C–H bond of will be broken at low potential to produce reactive H*. H* recombined Tafel step (H* + ⇌ H2) H2. At same time, oxidized high-value-added product HCOOH. We formation grain boundary-rich structures on Au–CuxO surface jointly promotes potentials. addition, introduced Ru elements into CuxO enhance cathodic HER. The FOR-HER system Au–CuxO/CF∥Ru–CuxO/CF was tested flow cell. produced current density 500 mA cm–2 only 0.38 V. This work provides construction catalyst design ideas voltages.
