Catalytic transformation of 2,5-furandicarboxylic acid to adipic acid over niobic acid-supported Pt nanoparticles

The conversion of biomass-derived molecules into adipic acid represents a highly attractive green route for sustainable production of adipic acid, a key monomer of nylon 66 and polyurethane. Here, we report the direct synthesis of adipic acid from 2,5-furandicarboxylic acid, which can be obtained from cellulose-based 5-hydroxymethylfurfural, using a niobic acid-supported platinum catalyst under hydrogen in water. Biomass-derived 2,5-furandicarboxylic acid was successfully converted to adipic acid over a niobic acid-supported Pt catalyst in water under H 2 .
