摘要:

2,5-呋喃二甲酸(FDCA)作为一种关键的生物质基平台化合物, 其绿色合成备受关注. 本文以稳定性优于5-羟甲基糠醛(HMF)的2,5-呋喃二甲醇(BHMF)为原料, 采用Pt/非晶碳(Pt/a-C)纳米材料为催化剂, 在温和条件下(1.45 V vs. RHE, 常温常压)实现了BHMF高效电催化氧化制备FDCA. 结果表明, Pt以纳米线形式通过Pt—C键均匀负载于非晶碳载体, 形成强界面相互作用; Pt/a-C的起始电位较商业Pt/C负移220 mV, Tafel斜率为34.63 mV/dec, 电荷转移电阻显著降低. 在1.45 V(vs. RHE)电位下, FDCA产率达92.80%, 法拉第效率为91.45%, 且循环5次后性能保持稳定. 机理研究揭示, 反应遵循双路径并行机制: BHMF经2,5-呋喃二甲醛(DFF)或5-羟甲基-2-呋喃甲酸(HMFCA)两条路径, 最终通过5-甲酰基-2-呋喃甲酸(FFCA)转化为 FDCA, Pt活性中心与载体的协同作用促进了反应动力学.

Abstract:

2,5-Furandicarboxylic acid(FDCA), as a key biomass-derived platform chemical, has attracted considerable attention for its green synthesis. In this study, 2,5-bis(hydroxymethyl)furan(BHMF), which exhibits higher stability than 5-hydroxymethylfurfural(HMF), was used as the feedstock. Pt/amorphous carbon(Pt/a-C) nanomaterials were employed as the catalyst to achieve efficient electrocatalytic oxidation of BHMF to FDCA under mild conditions(1.45 V vs. RHE, room temperature and ambient pressure). The results show that Pt nanowires are uniformly loaded onto the amorphous carbon support via Pt-C bonds, forming a strong interfacial interaction. Pt/a-C exhibits a 220 mV negative shift in onset potential compared to commercial Pt/C, with a Tafel slope of 34.63 mV/dec and a significantly reduced charge transfer resistance. At an applied potential of 1.45 V(vs. RHE), the FDCA yield reached 92.80% with a Faradaic efficiency of 91.45%, and the performance remains stable after five cycles. Mechanistic investigation reveals that the reaction follows a dual-pathway parallel mechanism: BHMF is converted FDCA via either 2,5-diformylfuran(DFF) or 5-hydroxymethyl-2-furancarboxylic acid(HMFCA), both ultimately proceeding through 5-formyl-2-furancarboxylic acid(FFCA) to FDCA. The synergistic effect between the Pt active sites and the support promotes the reaction kinetics. This study provides a new strategy for the green synthesis of biomass-based FDCA.
