Selective and green conversion of 5-HMF to FDCA <i>via</i> enzymatic (laccase) and transition metal (MnO₂ and Co-Mn/AC) catalysis in an integrated system.

ABSTRACT: The sustainable synthesis of bio-based monomers from renewable biomass intermediates is a central goal in green chemistry and biorefinery innovation. This study introduces a synergistic catalytic-enzymatic strategy for the efficient and eco-friendly oxidation of 5-hydroxymethylfurfural (5-HMF) into 2,5-furandicarboxylic acid (FDCA), a key monomer for next-generation biodegradable plastics. The catalytic phase employed non-noble metal catalysts, MnO₂ and Co-Mn supported on activated carbon (Co-Mn/AC), under mild batch reaction conditions at 90 °C. Through systematic optimization, a metal-modified catalyst composition was developed to enhance both conversion and selectivity. Complementing this, the enzymatic oxidation step utilized laccase, a sustainable biocatalyst, immobilized i
