The use of photocatalysis in conjunction with biomass presents an innovative and promising way to increase the sustainability chemical processes. In this work, a g-C3N4@AgFe2O4 heterojunction nanocomposite was prepared by facile sonication method subsequently modified sulfonic acid groups form new acidic photocatalyst enhanced photocatalytic activity. structure, surface composition, morphology, optical absorption features were studied using state-of-the-art characterization techniques. Visible-light-driven dehydration biomass-derived carbohydrates 5-hydroxymethylfurfural (HMF), as versatile platform compound, employed assess its catalytic property. Compared traditional homogeneous heterogeneous catalysts, reveled superior or equal activity production HMF from fructose only at low temperature (90 °C, 91% yield). easily recovered remained active recycle runs, approving good stability. Furthermore, developed protocol found be capable converting other feedstocks, such glucose, sucrose, maltose into respectable yields. Interestingly, work represents first example utilizing photocatalyst.

Abstract Electrocatalytic oxidation of biomass‐derived 5‐hydroxymethylfurfural (HMF) presents a promising pathway for synthesizing the value‐added chemical, 2,5‐furandicarboxylic acid (FDCA). However, it is still lack scalable strategies to fabricate electrocatalysts with high activity and selectivity. Herein, bayberry‐like Ni@Ni 3 S 2 core–shell catalyst prepared via spontaneous corrosion strategy HMF electro‐oxidation. The Ni shells abundant electron‐deficient sites facilitate generation high‐valence 3+ OOH active species. Additionally, in situ 2− SO 4 enhances electron proton transport capacity. Both high‐performance liquid chromatography (HPLC) density functional theory (DFT) analyses reveal that preferentially selects 2,5‐dicarboxyfurylfuran (DFF) due lower reaction energy barrier from DFF, rate‐determining step DFF generate 5‐formylfuran‐2‐carboxylic (FFCA) significantly accelerated. Consequently, yield FDCA Faraday efficiency are found be 99.20% 99.35%, respectively, they reach 88.79% 90.33% after ten cycles, showing excellent stability. Moreover, mass production 13.97 g successfully synthesized using strategy. This work offers valuable reference designing catalysts by manipulating routes achieve efficient biomass conversion.

Abstract Currently one‐pot conversion of sugars to 2,5‐furandicarboxylic acid (FDCA) is significant interest due the attainability as a feedstock and enormous potential FDCA bioplastic monomer. However, it remains challenging construct efficient catalysts for this process. In study, Co 3 O 4 species were anchored sulfonated covalent organic framework thus affording bifunctional catalyst (Co @COF‐SO H). The sulfonic sites dehydrate 5‐hydroxymethylfurfural (HMF), which next oxidized catalyzed by species. Such process was applied in various binary ternary deep eutectic mixtures involving choline chloride without additional solvent. maximum yield 84 % obtained using glucose‐fructose mixture substrates. Moreover, recyclable stable under reaction conditions. Our eliminates employment solvents expensive noble metal catalysts, resulting green economic biomass conversions.
