Catalytic Advances in the Production and Application of Biomass-Derived 2,5-Dihydroxymethylfuran

Abstract

In recent years, 2,5-dihydroxymethylfuran (DHMF), which can be produced by the selective hydrogenation of biomass-derived 5-hydroxymethylfurfural (HMF), has attracted great attention and interest of many scientists because of its peculiar symmetrical structure and wide potential applications. At present, studies of the production of DHMF are quickly progressing, with productive approaches being increasingly developed, and many crucial achievements have been continually obtained. However, to date, a special and real-time review of this research area is still lacking. To gain more insight into the current research situation, this review comprehensively summarizes and discusses state-of-the-art advancements of the production of DHMF from HMF via various chemocatalytic pathways, such as conventional hydrogenation, transfer hydrogenation, electrocatalytic hydrogenation, photocatalytic hydrogenation, disproportionation reaction, and biocatalytic pathways. Meanwhile, this review also systematically outlines the latest results on the further transformation of DHMF into value-added derivatives via etherification, polymerization, and rearrangement.

Catalytic Transfer Hydrogenation of Biomass‐Derived Substrates to Value‐Added Chemicals on Dual‐Function Catalysts: Opportunities and Challenges

“…Furfural hydrogenation to produce alcohols is known as one of the major routes for the production of transportation fuels in the past few years ,. We have not found any reports on CTH‐I of furfurals, which are also valuable intermediates for a variety of downstream products.…”

Ag Electrodeposited on Cu Open‐Cell Foams for the Selective Electroreduction of 5‐Hydroxymethylfurfural

“…Operating in a neutral media, Na 2 SO 4 and 0.05 M HMF, Ag shows the highest activity in 2,5‐bis(hydroxymethyl)furan (BHMF) formation, by reduction of the aldehyde to the alcohol, with a selectivity >85 % . In basic medium (borate buffer pH=9.2) with Ag modified Cu electrodes, the process is more selective towards the production of BHMF, a precursor of polymers . The morphology of the catalyst also plays a significant role.…”

“…[6] In basic medium (borate buffer pH = 9.2) with Ag modified Cu electrodes, [7] the process is more selective towards the production of BHMF, a precursor of polymers. [8] The morphology of the catalyst also plays a significant role. In the conversion of 0.02 M HMF over Ag/Cu in basic media solutions a 99 % selectivity and faradaic efficiency (FE) are achieved with electrocatalysts prepared by galvanic displacement of Cu by Ag.…”

Lewis Acid and Base Catalysis of YNbO4 Toward Aqueous‐Phase Conversion of Hexose and Triose Sugars to Lactic Acid in Water

“…[1][2][3] Cellulose and hemicellulose, the main components of non-edible woody biomass, have been identified as abundant and easily accessible resources for the future chemical industry. Selective hydrolysis of these insoluble oligosaccharide polymers affords soluble constituent sugars (glucose and xylose), [4,5] which can be further converted into diols (e. g., isosorbide, [6] ethylene glycol, [7] and 2,5-dihydroxymethylfuran [8] ) and carboxylic acids (e. g., furan 2,5-dicarboxylic acid, [9,10] lactic acid, [11] and succinic acid [12] ) that are building blocks for valueadded bio-based polymers. Many strategies that employ easily separable and reusable heterogeneous catalysts have been proposed for the production of platform molecules from woody biomass with an aim to realize the cost-effective production of bio-based commodity chemicals in a sustainable manner.…”
