Recent advances in the electrocatalytic synthesis of 2,5-furandicarboxylic acid from 5-(hydroxymethyl)furfural

Abstract

Biomass conversion and biorefinery provide a feasible and novel way to release the increasingly serious energy crisis and environmental deterioration. 2,5-furandicarboxylic acid (FDCA) has received increasing attention as a significant...

Selective Electrooxidation of Biomass‐Derived Alcohols to Aldehydes in a Neutral Medium: Promoted Water Dissociation over a Nickel‐Oxide‐Supported Ruthenium Single‐Atom Catalyst

“…The past years have witnessed a great progress in the development of the BDAOR, with efficient carboxylic acid production being extensively reported [13, 14] . Successful cases include 5‐hydroxymethylfurfural (HMF) oxidation to 2,5‐furandicarboxylic acid (FDCA), [15 16] and glycerol oxidation to formic acid [4, 11] .…”

Selective Electrooxidation of Biomass‐Derived Alcohols to Aldehydes in a Neutral Medium: Promoted Water Dissociation over a Nickel‐Oxide‐Supported Ruthenium Single‐Atom Catalyst

“…[10][11][12] The past years have witnessed a great progress in the development of the BDAOR, with efficient carboxylic acid production being extensively reported. [13,14] Successful cases include 5-hydroxymethylfurfural (HMF) oxidation to 2,5furandicarboxylic acid (FDCA), [15 16] and glycerol oxidation to formic acid. [4,11] Currently, alkaline electrolyte is the most used medium for the BDAORs, as non-noble metal-based catalysts are generally active and durable in such electrolyte.…”

Current Advances in the Sustainable Conversion of 5‐Hydroxymethylfurfural into 2,5‐Furandicarboxylic Acid

“…The synthetic process is driven, through electron migration under mild conditions, by the electrochemical potential, thus eliminating the need for any external oxidant. [75] The development of HMF electrochemical oxidation is gaining increasing importance since it mainly needs non-noble metal catalysts at ambient temperature. Another important feature of this process, which makes it even more interesting from an environmental point of view, is the concomitant production of H 2 that occurs at the cathode during the HMF anodic oxidation according to the following process [Eqs.…”

“…Indeed, homogeneous catalysts can get in close contact with the reactants, thus providing higher yields and better FE without any pH adjustment. [75] Choi et al [78] have reported that the use of 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) as a mediator greatly reduced the overpotential requirements for HMF oxidation by suppressing water oxidation, obtaining a 98 % yield with more than 93 % of FE. However, a noble metallic electrode (Au) and excess TEMPO were used, causing a high cost of the process.…”

“…The use of core-shell structures has also been widely investigated, and since 2018 a growing number of papers have been published on this subject since these catalysts possess active sites and conductive species at the same time. [75] Zhang et al [91] reported that a carbon-coupled nickel nitride nanosheet electrode provides a 98 % FDCA yield with a FE of almost 99 % even after 6 successive electrolysis cycles, highlighting the excellent stability of this catalyst. Recently, Deng et al [92] prepared copper sulfide nanowires/NiCo-LDH nanoarrays.…”
