Advances in enzymatic conversion of biomass derived furfural and 5-hydroxymethylfurfural to value-added chemicals and solvents

Heterogeneous catalytic oxidation of furfural with hydrogen peroxide over a niobia catalyst

“…26,27 These processes, conducted under aerobic or anaerobic conditions, [28][29][30][31][32] are capable of converting pentoses and their derivatives (e.g., furfural, HMF) into value-added products, such as furan-2,5-dicarboxylic acid (FDCA), furoic acid, and furfuryl alcohol. 27,33 The performance and selectivity of microorganisms can be improved through genetic modification methods. 27 This work explores oxidation of furfural with hydrogen peroxide using niobia as a heterogeneous catalyst, allowing a dramatic switch of the product selectivity from succinic and maleic acids to tartaric acid, never reported before in open literature.…”

Optimizing 5-hydroxymethylfurfural production from biomass carbohydrates: ionic liquid-catalyzed pathways in deep eutectic solvents under sonication and thermal conditions

“…7–10 This is because there are several side reactions that can occur during the acid-catalyzed dehydration of hexose materials, leading to the formation of unwanted by-products. 11–17 To overcome these challenges, researchers have developed various strategies to optimize the synthesis of 5-HMF and minimize the production of unwanted by-products. These include the use of mesoporous silica materials SBA-X (Santa Barbara amorphous), 18,19 are widely recognized as a top choice for immobilizing sulfonic acid groups, owing to their outstanding characteristics, including notable surface area, economical feasibility, and outstanding thermal stability, which can selectively promote the formation of 5-HMF while minimizing side reactions.…”

Industrially Promising β‐Ni(OH)2 Nanosheets Self‐Supported Electrode for Highly Efficient Electrooxidation of 5‐Hydroxymethylfurfural

“…Nowadays, various methods, including thermal-chemical catalysis, [10][11][12][13] bio-catalysis, [14,15] photocatalysis, [16] and electrocatalysis, [17] have been employed to convert HMF to FDCA. Electrochemical oxidation, in particular, stands out as a clean, environmentally friendly method with high product selectivity and ease of control, making it a promising green electro-synthesis technology.…”
