Abstract: The efficient conversion of biomass-derived 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA) is a major challenge under basefree conditions with inexpensive catalysts. We report a precious-metal-free recyclable MOF-based catalyst (CAU-28), constructed from the FDC ligand, with grafted redox-active Fe sites. This enables the conversion of HMF to FDCA under solvothermal heating or microwave-assisted methods in base-free aqueous conditions. The optimized process achieves 100% HMF conversion prod… Show more
