Catalytic Conversion of 2,5-Furandicarboxylic Acid Production from Hemicellulose

2,5-furandicarboxylic acid (FDCA), one of the most important building blocks, has attracted tremendous concerns, and the routes for FDCA synthesis from non-edible hemicellulose are of vital importance from the views of the circular economy. Herein, a multistep process towards hemicellulose-to-FDCA conversion is proposed, including hemicellulose-to-furfural conversion and sequential oxidation to furoic acid (FA), following with cesium furoate (FA-Cs) preparation and its direct carboxylation with carbon dioxide (CO2). The overall conversion yield of the targeted FDCA product towards the hemicellulose-to-FDCA pathway reaches 29.6
