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.

The oxidation of 5-HMF to HMFCA is an important yet complex process, as it generates high-value chemical intermediates. Achieving this transformation efficiently requires the development non-precious, highly active catalysts derived from renewable biomass sources. In work, we introduce UoM-1 (UoM, University Mazandaran), a novel cobalt-based metal-organic framework (Co-MOF) synthesized using simple one-step ultrasonic irradiation method. synthesis employed ligand 4,4'-((1E,1'E)-((5-carboxy-1,3-phenylene)bis(azaneylylidene))bis (methaneylylidene))dibenzoic acid (H3bdda). A comprehensive suite analytical techniques, including FT-IR, EDX, ICP, XRD, TEM, DLS, FESEM, and BET-BJH, was used confirm structural integrity material. catalytic performance investigated for selective conversion HMF HMFCA, demonstrating its effectiveness low-cost, accessible catalyst. To promote more sustainable environmentally friendly approach, reactions were performed in deep eutectic solvents, which offer green, low-energy alternative traditional solvents. This study shows that catalyst not only provides economical solution but also aligns with modern green chemistry principles, making promising candidate future applications.

Realizing high selectivity for producing biodegradable 2,5-bis(hydroxymethyl)tetrahydrofuran (BHMTHF) renewable polymers from 5-hydroxymethylfurfural (HMF) biomass through ring hydrogenation on single-atom catalysts poses a considerable challenge due to the complexity of HMF functional groups and difficulty H2 dissociation. We developed detailed reaction mechanism based ab initio molecular dynamics (AIMD) quantum mechanics (QM) find that Ru can simultaneously dissociate perform biomass-derived 2,5-bis(hydroxymethyl)furan (BHMF) produce BHMTHF, with free energy barrier 0.82 eV. The unique property sites enables easily single active site participate directly in without diffusion. Furthermore, our predicted rate microkinetic analysis indicates side-chain hydrogenolysis are much faster than ring-opening over range 300–550 K. product BHMTHF dominates 98.9% at 300 78.4% 550 K (the second is 5-methylfurfural (5-MFA)). This study underscores effectiveness atoms reactions using as hydrogen source, offering insights design other reactions.
