Resumen
The liquid phase transformation of 5-hydroxymethylfurfuraldehyde (5-HMF) towards 2,5-furandicarboxylicacid (2,5-FDCA) using Pt and Pd catalysts supported on activated carbon and with the presence of CaCO3 andNaOH, is reported. The catalysts were characterized using different techniques, such as: H2 chemisorptionat room temperature, X ray photoelectronic spectroscopy (XPS) and thermogravimetric analysis (TGA).The results indicate that the particle size followed the order: PtCl/C < PdCl/C < PdN/C, which is closelyrelated to the catalytic behavior. It was found that the metal particles are present in the Pd0 and Pt0 form.PtCl/C was most active catalyst using CaCO3 as weak base.
