Efficient catalytic oxidation of 5‐hydroxymethylfurfural to 2,5‐furandicarboxylic acid by magnetic laccase catalyst

2,5‐Furandicarboxylic acid (FDCA) is a biobased platform chemical for the production of polyesters. The magnetic laccase catalyst with TEMPO as the mediator has the remarkable capability of oxidizing 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 6 reuse cycles. Herein, this is the first report on the efficient catalytic oxidation of HMF to FDCA using an immobilized enzyme (magnetic laccase catalyst).
