Interaction of the conjugated structure in melanin contributed to photothermal conversion. Inspired by this, here, we first demonstrated that lignin nanoparticles (L-NPs) can carry out conversion, which was attributed π–π stacking molecules. Lignin be readily converted into L-NPs, using self-assembly method at room temperature. L-NPs showed a stable effect (22%). The were successfully used power thermoelectric generator and drive solar steam generation device under standard 1 sun irradiation (100 mW/cm2). Because generators technologies have huge potential for energy water purification, as-prepared are expected provide an important contribution sustainable clean production.

Fabrication of spherical lignin nanoparticles (LNPs) is opening more application opportunities for lignin. However, dissolution LNPs at a strongly alkaline pH or in common organic solvent systems has prevented their surface functionalization dispersion state as well processing and applications that require maintaining the particle morphology under harsh conditions. Here, we report simple method to stabilize through intraparticle cross-linking. Bisphenol A diglycidyl ether (BADGE), cross-linker that, like lignin, contains substituted benzene rings, coprecipitated with softwood Kraft form hybrid (hy-LNPs). The hy-LNPs BADGE content ≤20 wt % could be cross-linked without altering colloidal stability. Atomic force microscopy quartz crystal microbalance dissipation monitoring were used show internally particles resistant conditions acetone-water binary dissolved unmodified entirely. We further demonstrated covalent 12 an epoxy ring-opening reaction obtain pH-switchable charge. Moreover, ≥30% allowed both inter- cross-linking >150 °C, which enabled waterborne wood adhesives competitive dry/wet adhesive strength (5.4/3.5 MPa).

Abstract Thought-out utilization of entire lignocellulose is great importance to achieving sustainable and cost-effective biorefineries. However, there a trade-off between efficient carbohydrate lignin-to-chemical conversion yield. Here, we fractionate corn stover into fraction with high enzymatic digestibility reactive lignin satisfactory catalytic depolymerization activity using mild high-solid process aqueous diethylamine (DEA). During the fractionation, in situ amination achieves extensive delignification, effective stabilization, dramatically reduced nonproductive adsorption cellulase on substrate. Furthermore, by designing tandem fractionation-hydrogenolysis strategy, dissolved depolymerized aminated simultaneously co-produce monophenolics pyridine bases. The represents viable scheme transforming real bases yield, resulting from reactions cleaved side chains amines. This work opens promising approach valorization lignocellulose.
