摘要

2,5-Furandicarboxylic acid (FDCA) is a value added chemical that can be used as a polymer building block for the synthesis of biobased polymers. Developing efficient catalysts is fundamentally important for the selective oxidation of 5-hydroxymethylfurfural (HMF) into FDCA. In this work, a novel catalyst was prepared at mild conditions by forming platinum nanoparticles on a cerium coordination polymer (CeCP), which was synthesized using 1,3,5-benzenetricarboxylic acid as the ligand. The CeCP@Pt catalyst was utilized for the selective oxidation of highly concentrated HMF into FDCA. The yield of FDCA could reach 96.2% after 12 h of reaction at 70 degrees C in water at atmospheric conditions. Furthermore, this catalyst can be reused at least five times without significant activity loss. After five recycling cycles, the leaching of Pt from CeCP@Pt was negligible. This work demonstrated the advantages of the CeCP@Pt catalyst, including its easy preparation in mild conditions, application at relatively low temperatures and in atmospheric conditions, catalyzing the oxidation of HMF with a high concentration, and its reuse with a high stability.
