Publicación Acceso abierto Pt and Pd on activated carbon for oxidation of 5-hydr oxymethylfurfural to 2,5-furandicarboxylic acid(Universidad del Valle, 2017-07-01) Sanabria, Lyda; Lederhos, Cecilia; Quiroga, Mónica; Cubillos, Jairo; Rojas, Hugo; Martinez, José J.(Eng) In this work the transformation in liquid phase of 5-hydroxymethylfurfural (5-HMF) to 2,5-furandicarboxylic acid was studied with the use of Pt and Pd catalysts supported on activated carbon with the presence of NaOH or CaCO3. The catalysts were characterized by H2 chemisorption at room temperature, X-ray spectroscopy (XPS) and thermogravimetric analysis (TGA). The results indicate that the particle size of the catalysts follows the order PtCl / C
