Steering Selectivity in Electrocatalytic Furfural Reduction via Electrode–Electrolyte Interface Modification

Journal of the American Chemical Society, Journal Year: 2024, Volume and Issue: 146(17), P. 11876 - 11886

Published: April 16, 2024

Electrocatalytic reduction of biomass-derived furfural (FF) represents a sustainable route to produce furfuryl alcohol (FA) and 2-methylfuran (MF) as value-added chemical biofuel, respectively. However, achieving high selectivity for MF well tuning the between FA within one reaction system remain challenging. Herein, we have reported an electrode-electrolyte interface modification strategy, enabling steering under same conditions. Specifically, by modifying copper (Cu) electrocatalysts with butyl trimethylammonium bromide (BTAB), achieved dramatic shift in from producing (selectivity: 83.8%; Faradaic efficiency, FE: 68.9%) 80.1%; 74.8%). We demonstrated that BTAB adsorption over Cu modulates electrical double layer (EDL) structure, which repels interfacial water weakens hydrogen-bond (H-bond) network proton transfer, thus impeding FF-to-FA conversion suppression hydrogen atom transfer (HAT) process. On contrary, FF-to-MF was less affected. This work shows potential engineering control electrocatalysis.

Boosting electrochemical oxygen reduction to hydrogen peroxide coupled with organic oxidation

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: July 19, 2024

Abstract The electrochemical oxygen reduction reaction (ORR) to produce hydrogen peroxide (H 2 O ) is appealing due its sustainability. However, efficiency compromised by the competing 4e − ORR pathway. In this work, we report a hierarchical carbon nanosheet array electrode with single-atom Ni catalyst synthesized using organic molecule-intercalated layered double hydroxides as precursors. exhibits excellent 2e performance under alkaline conditions and achieves H yield rates of 0.73 mol g cat −1 h in H-cell 5.48 flow cell, outperforming most reported catalysts. experimental results show that atoms selectively adsorb , while nanosheets generate reactive species, synergistically enhancing production. Furthermore, coupling system integrating ethylene glycol oxidation significantly enhances rate 7.30 producing valuable glycolic acid. Moreover, convert electrolyte containing directly into downstream product sodium perborate reduce separation cost further. Techno-economic analysis validates economic viability system.
