2,5-Furandicarboxylic acid (FDCA) is a bio-based platform chemical for the production of polyethylene furanoate (PEF) and other valuable furanic chemicals. A magnetic laccase catalyst with (2,2,6,6-tetramethyl-piperidin-1-yl)oxyl (TEMPO) as the mediator has the remarkable capability of oxidizing 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA). Under optimal reaction conditions, a quantitative yield (90.2 %) of FDCA with complete HMF conversion was obtained after 96 h of reaction. More importantly, the magnetic laccase catalyst exhibited good recyclability and stability, maintaining 84.8 % of its original activity following six reuse cycles. This is the first report on the efficient catalytic oxidation of HMF to FDCA by using an immobilized enzyme catalyst.
2,5-呋喃二甲酸（FDCA）是一种生物基平台化学品，可用于生产聚呋喃酸酯（PEF）和其他有价值的呋喃类化学品。一种带有（2,2,6,6-四甲基-哌啶-1-基）氧（TEMPO）作为介体的磁性漆酶催化剂具有显著的氧化 5-羟甲基糠醛（HMF）为 2,5-呋喃二甲酸（FDCA）的能力。在最佳反应条件下，反应 96 h 后可定量获得 90.2%的 FDCA，HMF 转化率完全。更重要的是，磁性漆酶催化剂表现出良好的可回收性和稳定性，经过六次重复使用后，仍保持 84.8%的原始活性。这是首次报道使用固定化酶催化剂高效催化氧化 HMF 为 FDCA。
