摘要： 2,5-呋喃二甲酸（FDCA）是重要的生物质基平台化合物，其高效合成对生物质高值化利用具有重要意义。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，以Pt/无定形碳（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。表征结果表明，Pt以纳米线形式均匀负载于无定形碳载体，并通过Pt-C键形成强界面相互作用。电化学测试显示，Pt/a-C的起始电位较商业Pt/C负移218 mV，Tafel斜率为34.63 mV?dec?1，电荷转移电阻显著降低。在1.45 V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。机理研究表明，反应遵循"BHMF→羟醛中间体→FDCA"路径，Pt活性中心与载体的协同作用促进了反应动力学。该研究为生物质基FDCA的绿色合成提供了新策略。

Abstract: 2,5-Furandicarboxylic acid (FDCA) is a significant biomass-based platform compound, and its efficient synthesis holds great importance for the high-value utilization of biomass. In this study, 2,5-bis(hydroxymethyl)furan (BHMF), which exhibits superior stability compared to 5-hydroxymethylfurfural (HMF), was used as the feedstock. Employing Pt/amorphous carbon (Pt/a-C) nanomaterials as the catalyst, highly efficient electrocatalytic oxidation of BHMF to FDCA was achieved under mild conditions (1.45 V vs. RHE, room temperature and ambient pressure). Characterization results revealed that Pt was uniformly loaded onto the amorphous carbon support in the form of nanowires, forming a strong electron interaction interface via Pt–C bonds. Electrochemical tests demonstrated that the onset potential of Pt/a-C was negatively shifted by 218 mV compared to commercial Pt/C, with a Tafel slope of 34.63 mV?dec?1 and a significantly reduced charge transfer resistance. At a potential of 1.45 V, the FDCA yield reached 92.80% with a Faradaic efficiency of 91.45%, and the performance remained stable after five cycles. Mechanistic studies indicated that the reaction follows a pathway of "BHMF → aldol intermediate → FDCA," with the synergistic effect between the Pt active sites and the support promoting the reaction kinetics. This research provides a novel strategy for the green synthesis of biomass-based FDCA.
