Ce‐Doping Rather Than CeO₂ Modification and Their Synergistic Effect: Promotion from Ce Species in the Electrocatalytic Oxidation of 5‐Hydroxymethylfurfural Over NiFe–LDH

Advanced Energy Materials, Год журнала: 2024, Номер 14(38)

Опубликована: Июль 11, 2024

Abstract Electrocatalytic oxidation of 5‐hydroxymethylfurfural (HMFOR) is an effective route to produce value‐added chemicals with low energy consumption. In this work, efficient electrocatalysts are prepared by varying the amount Ce doping and CeO 2 modification on NiFe layered double hydroxide (NiFe–LDH) nanosheets supported carbon cloth (CC). Through heterogeneous interface construction, electronic structure coordination chemistry NiFe–LDH greatly changed. Compared synergistic effect Ce‐doping modification, CC@NiFeCe(3%)‐LDH only show excellent charge transfer ability, higher HMF conversion (95.73%), 2,5‐furandicarboxylic acid (FDCA) selectivity (93.31%), Faraday efficiency (99.47%) at 1.44 V RHE . Density‐functional theory calculations X‐ray fine spectroscopy demonstrate that doping, compared their effects, significantly facilitates electron transport optimizes intermediate adsorption effectively lowering activation for transformation 5‐formyl‐2‐furancarboxylic (FFCA) encourage FFCA FDCA. Overall, work systemically investigates HMFOR behaviors CC@NiFe–LDH under synergetic effect, which provides some guidance development high‐performance performance.

The electrochemical oxidation of 5-hydroxymethylfurfural (HMF) is an efficient method to produce 2,5-furandicarboxylic acid (FDCA). moderate alkaline condition (pH ≈ 13) a compromise between stability concern and catalytic efficiency. Herein, several critical issues are studied improve the HMF FDCA in 0.1 M KOH using NiO as catalyst. direct process observed before formation Ni3+ species, which follows reaction mechanism. By increasing electrode area/electrolyte volume ratio loading, potential can be extended lower value (1.30 VRHE) with high yield (>95%). Moreover, 97% realized at feeding concentration 40 mM by anion exchange membrane (AEM) separator H-type electrolyzer three-electrode system. In addition, adsorption products electrolysis system compound penetration through AEM from anolyte catholyte cannot ignored two-electrode flow cell. slight decrease alkali conducive decreasing due inhibition water transfer opposite direction AEM.
