“…The literature survey for the oxidation of HMF to FDCA indicated that this reaction has been performed using stoichiometric amounts of oxidants and expensive catalytic systems containing noble metals such as Pt [17][18][19][20][21][22], Pd [23][24][25][26], Au [27][28][29][30][31][32], Ru [33], or their alloys [34][35][36][37][38][39][40][41]. In addition, the presence of a base is crucial in order to facilitate the desorption of the resulted acid from the catalytic surface.…”

“…Recently, Karimi and coworkers employed a magnetically separable catalyst (Fe 3 O 4 @SiO 2 -TEMPO) for the selective oxidation of HMF to DFF under metal-and halogen-free conditions. [19] In addition to organic catalysis, a series of transition-metal catalysts, such as vanadium, [20][21][22][23] manganese, [24,25] cobalt, [26] ruthenium, [27][28][29][30] copper, [31] iron, [32] silver, [33] and palladium, [34] were recently developed for HMF-to-DFF transformation and HMF conversion into 2,5-furandicarboxylic acid (FDCA) with molecular oxygen or air as the oxidants under a milder and more sustainable route.…”

A series of acidic cesium salts of molybdovanadophosphoric heteropolyacids (CsMVP‐HPAs) are developed as bifunctional and recyclable catalysts for a one‐step approach to 2,5‐diformylfuran (DFF) from fructose with molecular oxygen as the oxidant under environmentally benign conditions. The CsMVP‐HPAs afford the direct synthesis of DFF from fructose through acidic site (H)‐promoted fructose dehydration and metallic site (V)‐catalyzed successive aerobic oxidation of 5‐hydroxymethylfurfural (HMF). The catalytic performances of CsMVP‐HPA toward fructose dehydration and HMF oxidation are related to its acid density and V content, respectively. Moreover, the increase in the V content of CsMVP‐HPA results in its decreased acid density, which suggests its converse catalytic performance toward fructose dehydration and HMF oxidation. An optimum balance between the dehydration and oxidation functions of CsMVP‐HPAs reveals that a ratio of acid density to molar concentration of V between 1.64 and 3.34 achieves a maximum yield of 60 % for DFF from fructose with Cs3HPMo11VO40 as a catalyst under atmospheric pressure of oxygen. Moreover, Cs3HPMo11VO40 behaves as a heterogeneous catalyst and can be easily reused at least for four times. This research highlights an efficient bifunctional catalyst for transforming renewables into fine chemicals in tandem reactions of dehydration and oxidation.

“…However, Au catalysts are less efficient in the oxidation of the hydroxyl group that oxidation of the carbonyl group, and the presence of additives or basic supports is necessary, to reach the oxidation of 5-HMF to 2,5-FDCA. Casanova et al (12), claim that the oxidation of 5-HMF is very selective to 2,5-FDCA, with yield 99% under mild conditions (65-130 °C, 10 bar air pressure and water as solvent) with nanoparticles gold supported on cerium oxide (Au-CeO 2 ) and titanium oxide (AuTiO 2 ) as catalysts; being the first the most active and selective (13 (14). It was obtained a high selectivity of 90% to 2,5-FDCA, possibly due to the basicity of the reaction medium.…”

The liquid phase transformation of 5-hydroxymethylfurfuraldehyde (5-HMF) towards 2,5-furandicarboxylic acid (2,5-FDCA) using Pt and Pd catalysts supported on activated carbon and with the presence of CaCO 3 and NaOH, is reported. The catalysts were characterized using different techniques, such as: H 2 chemisorption at 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 closely related to the catalytic behavior. It was found that the metal particles are present in the Pd 0 and Pt 0 form. PtCl/C was most active catalyst using CaCO 3 as weak base. Keywords: Aerobic oxidation, activated carbon, 2,5-furandicarboxylic acid. ResumenEn este trabajo se estudió la transformación en fase líquida de 5 hidroximetilfurfural (5-HMF) a ácido 2,5-furandicarboxilico con el uso de catalizadores de Pt y Pd soportados en carbón activado con la presencia de NaOH ó CaCO 3 . Los catalizadores fueron caracterizados por quimisorción de H 2 a temperatura ambiente, espectroscopia de rayos X (XPS) y análisis termogravimétrico (TGA). Los resultados indican que el tamaño de partícula de los catalizadores sigue el orden PtCl/C < PdCl/C < PdN/C el cual esta estrechamente relacionado con la actividad catalítica. Se encontró que las partículas metálicas están presentes como especies de Pd 0 and Pt 0 . Siendo el catalizador de Pt-Cl/C con el uso de CaCO 3 como aditivo.Palabras clave: Ácido 2,5-furandicarboxilico, carbón activado, oxidación aeróbica.
