Abstract The conversion of lignin into aviation fuel offers a promising, energy‐efficient route for sustainable jet production. key to this transformation lies in the selective hydrogenation lignin's aromatic rings, deoxygenation its oxygen‐containing and phenolic hydroxyl groups, cleavage bonds between polycyclic hydrocarbons. Using phosphorus‐doped CoMn‐P catalyst, electrochemical lignin, assisted by light, can reduce energy consumption ≈20%, resulting significant yield hydrocarbons cycloalkanes. Phosphorus doping modulates catalyst's electronic structure, enhancing adsorption β─O─4 bonds, methoxy thereby enabling with low reaction barrier. This approach provides an innovative pathway directly converting hydrocarbon mixtures suitable fuel.

Abstract To overcome the challenges of low catalytic activity and instability, a molecular weight engineering strategy coupled with oxidative ammonolysis is developed to synthesize CoRu‐based alloy catalysts distinct morphologies properties from biorefinery lignin. This approach effectively modulates intrinsic active sites exposes unsaturated nitrogen‐oxygen structures, thereby tailoring morphology defect structure carbon layers in catalysts. The as‐synthesized CoRu lignin precursors varying weights are designated as CoRu@OALC‐EtOAC, CoRu@OALC‐EtOH, CoRu@OALC‐Residual. featuring defect‐rich graphitic carbon‐coated structure, exhibited exceptional overall water‐splitting performance (1.48 V at 10 mA cm −2 ), significantly surpassing Pt/C || Ru/C (1.58 ). In contrast, CoRu@OALC‐Residual, its amorphous demonstrated remarkable stability (350 h 100 vastly outperforming (6 In‐situ Raman spectroscopy DFT calculations revealed that adsorb * H intermediates, accelerating process. strong adsorption also induces layer rearrangement, leading dissolution oxidation metal particles. provides universal method for biomass‐derived catalysts, establishing direct relationship between weight, catalyst morphology, electrocatalytic performance.

The low-cost and high-capacity SiOx is widely recognized as an ideal anode material for lithium storage; however, the challenges of low conductivity significant volume expansion still need to be addressed. In this work, we incorporated into a lignin-derived carbon with elevated nitrogen content through step-by-step carbonization strategy. Initially, electrostatic assembly facilitated formation complex comprising modified lignin SiO2, which was subsequently subjected etching steps. Finally, due zinc species inhibiting decomposition, cocarbonization porous carbon/SiOx complex, oxalate, melamine enabled construction nitrogen-enriched composite. resulting composite exhibited moderate specific surface area, abundant mesoporous channels, exceptionally high doping 17.91 at. %. These characteristics effectively enhanced storage transportation ions while mitigating expansion. As anodes in half batteries, reversible capacity optimized reached 894 mAh/g during stable cycles, attributed ion diffusion rate kinetics from well improved structural stability encapsulated structure. Furthermore, assembled lithium-ion capacitor demonstrated energy density 82 Wh/kg maintained retention 93.1% after undergoing 15,000 cycles. This work presents novel concept synthesis nitrogen-rich matrixes but also offers insights optimization silicon-based negative electrodes using green biomass.

Single-atom catalysts (SACs) have attracted considerable interest in the field of electrocatalysis due to their high efficiency metal utilization and catalytic activity. However, traditional methods SACs fabrication are often complex time-consuming. Herein, F-Ru@TiO x N y was synthesized using a straightforward universal approach via situ surface etching heteroatoms immobilization on vacancies-rich hierarchical TiO nanorods array. The fluorine ion-etched could produce abundant oxygen vacancies F-Ti/F-C bonds, which capture stabilize Ru by strong host-guest electronic interactions. Due synergistic effect anchoring F-C bonds-assisted stabilization single atoms, revealed excellent electrocatalytic hydrogen evolution performance, low overpotential 20.8 mV at 10 mA cm-2, Tafel slope 59.9 dec-1 robust stability 100 cm-2 over 48 h. Furthermore, this strategy be applicable various heterometals (Pd, Ir, Pt), also exhibited dispersity HER activity/stability. This method is simple, easy-scalable versatile, showcasing significant potential for electrocatalysts design promising application prospects energy conversion.
