biostudies-literatureUnknown16(1)Jiang XElectrocatalytic 5-hydroxymethylfurfural oxidation reaction (HMFOR) provides a promising strategy to convert biomass derivative to high-value-added chemicals. Herein, a cascade strategy is proposed to construct Pd-NiCo₂O₄ electrocatalyst by Pd loading on Ni-doped Co₃O₄ and for highly active and stable synergistic HMF oxidation. An elevated current density of 800 mA cm^-2 can be achieved at 1.5 V, and both Faradaic efficiency and yield of 2,5-furandicarboxylic acid remained close to 100% over 10 consecutive electrolysis. Experimental and theoretical results unveil that the introduction of Pd atoms can modulate the local electronic structure of Ni/Co, which not only balances the competitive adsorption of HMF and OH^- species, buNano-micro letters275https://www.ebi.ac.uk/biostudies/studies/S-EPMC11339012biostudies-literatureEnhancing the Electrocatalytic Oxidation of 5-Hydroxymethylfurfural Through Cascade Structure Tuning for Highly Stable Biomass Upgrading.PMC11339012Liu YYang YZhao LWang PZhang YJiang XMa XLin YWei YfalseEnhancing the Electrocatalytic Oxidation of 5-Hydroxymethylfurfural Through Cascade Structure Tuning for Highly Stable Biomass Upgrading.Electrocatalytic 5-hydroxymethylfurfural oxidation reaction (HMFOR) provides a promising strategy to convert biomass derivative to high-value-added chemicals.
