Article Abstract
Catalytic conversion of biomass-derived value-added chemicals was of great significance for the utilization of renewable biomass resources to instead of fossil chemicals. Biomass-derived lignin was regarded as an important support and 5-hydroxymethylfurfural (HMF) was a vital platform chemical derived from cellulose. Herein, a series of lignin-MOF hybrid catalysts were prepared and modified with different heteropolyacids (HPAs), which were then successfully introduced into the selective conversion of HMF to 5-hydroxymethylfurfuryl alcohol (MFA). The effect of different HPA, calcination temperature, etc. were all studied, and all catalysts were well characterized. It was confirmed that silicotungstic acid modified catalyst (NiCo-MOF-LS@HSiW) exhibited the best catalytic performance, while the highest conversion of HMF was up to 100%, with the best MFA yield of 86.5%. The finding in this study could provide novel insights for the utilization of lignin and preparation of value-added biomass-derived chemicals.

Worldwide, marine shell waste generated from the seafood industry has emerged as a significant environmental challenge. Indeed, this shell waste represents an abundant source of various valuable products, particularly chitin. However, the extraction and subsequent processing of chitin are hindered by the inherently resistant structure of these chitin-rich feedstocks, coupled with strong hydrogen bonding between chitin chains.

Electrocatalytic coupling of nitrate reduction (NORR) to ammonia with 5-hydroxymethylfurfural (HMF) oxidation to 2,5-furandicarboxylic acid (FDCA) enables simultaneous wastewater remediation and biomass valorization. However, developing efficient bifunctional electrocatalysts for these multiproton-coupled electron transfer reactions remains challenging as conventional single-active-site catalysts inherently suffer from linear scaling relationships between intermediates and adsorption energies, particularly sluggish proton transfer. To address this, we engineered a triphasic N-doped CuO@CoO@Ni(OH) heterostructure with a gradient built-in electric field (BIEF), which synergistically enhances interfacial charge polarization and accelerates proton transport through dynamic coupling effects in both reactions: sufficient *H supply for NORR and fast Ni(OH)/NiOOH redox cycling during HMF oxidation (HMFOR), thus achieving unprecedented bifunctional performance: at - 0.

2,5-Furandicarboxylic acid (FDCA), synthesized via selective oxidation of 5-hydroxymethylfurfural (HMF), is a structural analog to petroleum-derived terephthalic acid (PTA) and a key precursor for renewable polyesters like polyethylene furanoate (PEF). Recent advances in electrocatalytic HMF oxidation (HMFOR) enable efficient synthesis under mild conditions, aligning with renewable energy integration. In this work, catalysts with oxygen-rich vacancies by growing Ce, V bimetallic-dopsynthesizeded Ni(OH) nanosheets in situ on nickel foam for electrocatalytic HMF oxidation to FDCA are prepared.

We report a stable and selective photocatalyst for solar-driven oxidation of 5-hydroxymethylfurfural (HMF) using TiO coated CsPbBr quantum dots (QDs). Controlled TiO encapsulation at 120 °C preserves the structural integrity of the QDs, enhances colloidal stability, and forms a type II heterojunction that facilitates charge separation. The optimized nanocomposite achieves high conversion to 2,5-diformylfuran (DFF) with 90% selectivity under visible light irradiation using TEMPO as a redox mediator.
