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.

Abstract Electrocatalytic hydrogenation of unsaturated aldehydes to alcohols is a promising alternative conventional thermal processes. Both the catalyst and electrolyte deeply impact performance. Designing electrode‐electrolyte interface remains challenging due its compositional structural complexity. Here, we employ electrocatalytic 5‐hydroxymethylfurfural (HMF) as reaction model. The typical cationic surfactant, cetyltrimethylammonium bromide (CTAB), analogs are employed additives tune interfacial microenvironment, delivering high‐efficiency HMF inhibition hydrogen evolution (HER). surfactants experience conformational transformation from stochastic distribution directional assembly under applied potential. This oriented arrangement hampers transfer water molecules promotes enrichment reactants. In addition, near 100 % 2,5‐bis(hydroxymethyl)furan (BHMF) selectivity achieved, faradaic efficiency (FE) BHMF improved 61 74 at −100 mA cm −2 . Notably, microenvironmental modulation strategy applies range reactions involving aldehyde substrates. work paves way for engineering advanced interfaces boosting alcohol electrosynthesis efficiency.

Abstract Solar‐driven upgrading of biomass‐derived 5‐hydroxylmethylfurfural (HMF) to 2,5‐furandicarboxylic acid (FDCA) holds great promise for sustainable production bio‐plastics and resins. However, the process is limited by poor selectivity sluggish kinetics due vertical coordination HMF at relatively strong metal sites. Here, we purposely developed a Cu(II) porphyrin framework featuring side‐chain incorporated urea linkages, denoted as TBUPP−Cu MOF, render weak hydrogen bond site flat adsorption via π–π stacking with benzene moiety. The unique configuration promotes approaching −CHO photoexcited ring towards kinetically thermodynamically favourable intermediate formation subsequent desorption. charge localisation orbital energy alignment enable selective activation O 2 over generate ⋅O − 1 instead highly oxidative H ⋅OH spin‐flip electron transfer, which drive ambient oxidation proximal −CHO. effective utilisation redox species circumvented over‐oxidation facilitate FDCA >90 % high turnover number 193 mol Cu −1 . facile purification high‐purity zero‐waste recycling intermediates durable catalyst feature MOF promising photo‐oxidation platform net‐zero biorefining organic transformations.
