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.

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.

ConspectusFor sustainable development, exploring renewable resources is an urgent priority. Nonfood biomass, one of the largest on Earth, primarily comprises three key components: lignin (ca. 15-30%), cellulose 35-50%), and hemicellulose 20-30%). Theoretically, nonfood biomass can be converted into green chemicals energy. However, most studies have focused generation carbon-based energy under harsh conditions, often resulting in lower selectivities. Therefore, further efforts to explore efficient selective methods for producing hydrogen (H2) are essential promoting practical applications biomass. In this Account, we summarize our contributions transformation its derivatives aryl compounds H2. These transformations were achieved using visible-light-induced photocatalytic systems that generate active radicals selectively cleave C-C, C-O, C-H, O-H bonds mild without noble metals. First, compound production was by chemoselective cleavage C-C C-O carboxyl ether radical cations. Specifically, charge-transfer complex induced carboxylic acids, which platform molecules derived from oxidation; free form facilitated model 4-O-5 linkage. Moreover, arenols alcohols obtained via cooperation cation vanadate-induced models various linkages. Second, developed a streamlined strategy H2 one-pot, two-step route with formic acid (HCO2H) as intermediate storage thermocatalysis. Using photoredox catalysis, HCO2H initially alkoxy radical-induced gradual cellulose, hemicellulose, glucose, their derivatives. Subsequently, biomass-based realized hydroxyl (·OH)-induced C-H following bonds, nickel catalysis. Third, highest capability water reforming. This process utilized followed generated carbon cations electrocatalysis, inducing well-organized O-H, bonds. We anticipate these insights will inspire development more efficient, stable, cost-effective catalytic systems, accelerating utilization resource driving other related significant transformations.
