A novel platinum nanocatalyst for the oxidation of 5-Hydroxymethylfurfural into 2,5-Furandicarboxylic acid under mild conditions

Selective oxidation of 5-hydroxymethyl furfural over non-precious metal heterogeneous catalysts

“…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.…”

Selective Aerobic Oxidation of 5‐HMF into 2,5‐Furandicarboxylic Acid with Pt Catalysts Supported on TiO2‐ and ZrO2‐Based Supports

“…[29] More recently, carbon nanotube (CNT)-supported AuÀPd catalysts achieved total HMF conversion with a yield of 94 % FDCA in 12 h in water under basefree conditions (T = 100 8C under P = 5 bar O 2 ; HMF/(Au + Pd) = 100). [30] A stable Fe III -polymer containing basic porphyrin subunits was proposed.…”

“…[30] A stable Fe III -polymer containing basic porphyrin subunits was proposed. [31] It should be highlighted that, to be effective under base-free conditions, the catalysts must be loaded with a low HMF to metal molar ratio, typically in the range 20-40, [18,29] or they require higher temperatures and longer reaction times compared with reactions performed with the addition of base. [30] Even if it would be a more ecofriendly and safe to perform reactions in water, improved catalysts are still needed.…”

Novel Catalytic Systems to Convert Chitin and Lignin into Valuable Chemicals

“…Hydrolysis of cellulose [13,14] provides monosaccharides as the major product, whereas hydrogenolysis leads to the formation of polyols [15,16]. Hydroxymethylfurfural (5-HMF) is a versatile building block chemical derived from cellulose, which can be further transformed into a wide range of high value chemicals such as adipic acid and 2,5-furandicarboxylic acid [17][18][19].…”
