Strong and Fireproof Regenerated Wood via a Combined Phosphorylation-Surface Nanofibrillation and Ionic Cross-Linking Strategy

ACS Nano, Год журнала: 2025, Номер unknown

Опубликована: Янв. 17, 2025

To reduce the environmental impact of plastics, an increasing number high-performance sustainable materials have emerged. Among them, wood-based structural gained growing attention due to their outstanding mechanical and thermal properties. Here, we introduce phosphate groups onto wood veneers for surface nanofibrillation, effectively altering both molecular structure morphology wood, which enhances interactions between endows with excellent fire resistance With these phosphorylated building blocks, "chemical welding" (CWSMs) obtained through chemical cross-linking exhibit The flexural strength CWSM reaches 225 MPa, modulus 16 GPa, surpassing those various types natural wood. At same time, phosphorylation has endowed resistance, a limiting oxygen index reaching 49%, making it completely noncombustible. More importantly, as biomass-based material, exhibits mechanical, thermal, properties degradability far superior traditional petroleum-based ideal candidate plastic replacement.

Photothermal catalytic transfer hydrogenolysis of protolignin

Nature Communications, Год журнала: 2024, Номер 15(1)

Опубликована: Ноя. 23, 2024

Abstract Photothermal catalysis is a promising strategy to combine the advantages of both thermal-catalysis and photocatalysis. Herein we achieve protolignin conversion aromatics via photothermal catalytic transfer hydrogenolysis process intensified by in-situ protection strategy. The Pd/TiO 2 at 140 °C with UV irradiation can catalyze reforming primary alcohols aldehydes active H* species, which further participate in acetalation 1,3-diol group β-O-4 linkage mediate C β –OAr bonds, respectively. birch sawdust ethanol as hydrogen donor provides 40 wt% yield phenolic monomers, compared an 11 monomer obtained from extracted 1,3-diol-protected lignin under same conditions. synergistic effect photocatalysis contributes prior cleavage bond before other C–O bonds. feasibility solar-light-driven system demonstrated.
