Abstract
A method for preparing 2,5-furandicarboxylic acid (FDCA) by oxidizing 5-hydroxymethylfurfural (HMF) in water in the presence of a weak base and a supported catalyst comprising platinum and bismuth, in which the Bi/Pt molar ratio in the catalyst is between 0.1 and 0.3, and preferably between 0.15 and 0.3.
