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.
