摘　　要：在第75届联合国大会上,我国承诺力争在2030年前实现碳达峰、2060年前实现碳中和。主要由光合作用产生的生物质将在双碳目标中扮演重要角色,通过高效转化可衍生出一系列替代化石产品的高值化学品。其中,2,5-呋喃二甲酸(FDCA)由于具有与石油基对苯二甲酸(TPA)相似的共轭碳环和二酸结构,可替代TPA用于合成热稳定性能、气体阻隔性能更优的生物基呋喃聚酯,大幅降低聚酯行业对化石资源的严重依赖。此外,FDCA在医药、香料、金属配位化学方面也有广泛应用,从而被认为是12种最具潜力的生物基平台化合物之一。FDCA通常可由5-羟甲基糠醛(HMF)通过催化氧化进行合成。相比于需要贵金属催化剂、高温和高压条件、以化学势作为驱动力的传统热催化方法,电催化氧化采用电极电势作为主要驱动力,是更为绿色和高效的新颖合成方法。本综述对电催化氧化制备FDCA反应所用的贵金属、过渡金属和非金属催化剂进行了总结与分析,梳理了催化剂设计和反应机理的研究脉络,并指出了该领域发展所面临的挑战与机遇。At the 75th session of the United Nations General Assembly,China made a solemn commitment to strive to achieve carbon peaking by 2030 and carbon neutrality by 2060.Biomass,mainly produced by photosynthesis,will play an important role in the dual carbon targets.The efficient conversion of biomass can yield a range of high-value chemicals to replace fossil-derived products.Among these biomasses,2,5-furandicarboxylic acid(FDCA)can be used to replace petroleum-based terephthalic acid(TPA)in the synthesis of bio-based furan polyesters with better thermal stability and gas barrier properties due to its similar conjugated carbon ring and diacid structure to TPA,significantly reducing the heavy reliance on fossil resources in polyester industry.In addition,FDCA is widely applied to pharmaceuticals,fragrances and metal coordination chemistry,making it one of the twelve most promising bio-based platform compounds.FDCA is typically synthesized by catalytic oxidation of 5-hydroxymethyl furfural(HMF).Compared to conventional thermocatalytic methods that require precious metal catalysts,high temperature and pressure conditions,and chemical potential as the driving force,electrocatalytic oxidation uses electrode potential as the main driving force and is a novel synthesis method that is greener and more efficient.This review summarises and analyzes the noble metal,transition metal and non-metal catalysts used in the preparation of FDCA reactions by electrocatalytic oxidation,outlines the research on catalyst design and reaction mechanisms,and points out the challenges and opportunities for the development of this field.
