Abstract

2,5-Furandicarboxylic acid (FDCA) is a promising biomass-derived alternative to fossil-based terephthalic acid. The catalytic oxidation of 5-hydroxymethylfurfural (HMF) to FDCA is widely recognized as a viable route for producing FDCA at industrially relevant concentrations (approximately 20 wt %); however, this has not yet been achieved. Toward this goal, we report that through controlled engineering of an oxygen-vacancy-enriched Mn/Co oxide as the support for Pt nanoparticles, a heterostructure of Pt/PtO₂ with electron-rich interfacial Pt–O–Mn sites (Pt/Mn₁₀Co₁O_x-VC) is formed, significantly enhancing the adsorption and activation of O₂, HMF, and its key intermediates. As a result, selective oxidation of both HMF (up to 40 wt %) and crude HMF (10 wt % and 70 wt % purity) was achieved with high FDCA yields ranging from 83% to 95% under base-free conditions, demonstrating strong economic feasibility and industrial potential for FDCA production. This work highlights the rational design of interfacial structures for the efficient oxidation of biomass-derived aldehydes and alcohols to bio-based dicarboxylic acids at industrially relevant concentrations, paving the way for FDCA to serve as a sustainable alternative to terephthalic acid as a comonomer in polyester production.

以工业水平的浓度生产生物质塑料单体 2,5-呋喃二甲酸

2,5-呋喃二甲酸（FDCA）是一种很有前景的生物质替代化石对苯二甲酸的来源。5-hydroxymethylfurfural (HMF) 催化氧化成 FDCA 被广泛认为是生产工业相关浓度（约 20 wt %）FDCA 的可行途径；然而，这一目标尚未实现。为了实现这一目标，我们报告了通过对作为铂纳米粒子支撑的氧空位富集锰/钴氧化物进行控制工程，形成了具有富电子界面铂-氧-锰位点（Pt/Mn10Co1Ox-VC）的异质结构 Pt/PtO2，显著增强了对 O2、HMF 及其关键中间产物的吸附和活化。因此，在无碱条件下，HMF（纯度高达 40 wt %）和粗 HMF（纯度分别为 10 wt % 和 70 wt %）都实现了选择性氧化，FDCA 产率高达 83% 至 95%，证明了 FDCA 生产具有很强的经济可行性和工业潜力。这项工作强调了界面结构的合理设计，可在工业相关浓度下将生物质衍生醛和醇高效氧化为生物基二羧酸，为 FDCA 在聚酯生产中作为对苯二甲酸的可持续替代共聚单体铺平了道路。
