Industry-oriented method for the aqueous phase oxidation of crude 5-hydroxymethyl furfural (HMF) to 2,5-furandicarboxylic acid (FDCA)

Abstract

Valorization of cellulose, hemicellulose and lignin into value-added industrially relevant chemicals is important to achieve sustainability goals that various governments and industries have set. In view of this, oxidative synthesis...

Manganese oxide-based catalysts for the sustainable synthesis of value-added chemicals through oxidation processes: a critical review and perspectives for the future

“…FDCA is an excellent biomass compound as an alternative to terephthalic acid in the field of polymers. 123,124 Therefore, various MnO x -based catalysts have been achieved in the aerobic oxidation of HMF to FDCA (Table 4).…”

Effect of K+ and Ca2+ Cations on Structural Manganese(IV) Oxide for the Aerobic Oxidation of 5-Hydroxymethylfurfural to 2,5-Furandicarboxylic Acid

“…In the current research regime of FDCA production, heterogeneous catalysts have been more attractively developed due to the stability and reusability. The oxidative catalytic methods have been extensively studied in various process of noble metals [gold (Au), , palladium (Pd), platinum (Pt), rhodium (Rh), and ruthenium (Ru) and non-noble metals [cerium (Ce), cobalt (Co), iron (Fe), and manganese (Mn) − ] supported heterogeneous catalysts. Moreover, the nonbase oxidation of HMF was studied over the Co–Mn–Br catalysts to produce high yield of FDCA. − Interestingly, a promising nonprecious manganese oxide (MnO 2 ) could act as an effective heterogeneous catalysts for the aerobic oxidation of HMF to FDCA in which the catalytic performance was determined by the oxygen vacancy formation. , Recently, calcium manganese oxide has been taken as an inspiration to achieve the goals of biomimetic oxygen-evolving catalysts and organic sulfide oxidation. − Although the calcium manganese oxides have been used to support of Pd nanoparticles (PdNPs) in HMF oxidation, their catalytic properties of bare support materials remain a challenge in this field to reveal the synergistic interactions .…”
