Synthesis of Sustainable Lignin Precursors for Hierarchical Porous Carbons and Their Efficient Performance in Energy Storage Applications

ACS Sustainable Chemistry & Engineering, Год журнала: 2024, Номер 12(6), С. 2352 - 2363

Опубликована: Янв. 23, 2024

Lignin-derived porous carbons have great potential for energy storage applications. However, their traditional synthesis requires highly corrosive activating agents in order to produce structures. In this work, an environmentally friendly and unique method has been developed preparing lignin-based 3D spherical (LSPCs). Dropwise injection of a lignin solution containing PVA sacrificial templates into liquid nitrogen produces tiny spheres that are lyophilized carbonized LSPCs. Most the synthesized samples possess excellent specific surface areas (426.6–790.5 m2/g) along with hierarchical micro- mesoporous morphologies. When tested supercapacitor applications, LSPC-28 demonstrates superior capacitance 102.3 F/g at 0.5 A/g, rate capability 70.3% retention 20 commendable density 2.1 Wh/kg 250 W/kg. These materials (LSPC-46) also show promising performance as anode material sodium-ion batteries high reversible capacity (110 mAh g–1 100 mA g–1), Coulombic efficiency, cycling stability. This novel green technique is anticipated facilitate scalability open range research opportunities

Highly-efficient sustainable ionic thermoelectric materials using lignin-derived hydrogels

Advanced Composites and Hybrid Materials, Год журнала: 2024, Номер 7(2)

Опубликована: Март 1, 2024

Abstract The efficient and economical conversion of low-grade waste heat into electricity has promising potential to combat the greenhouse effect expedite shift towards sustainable development. This study presents an innovative appealing approach through utilization lignin, abundant product derived from paper pulp industry, develop hydrogels as compelling materials for application in ionic thermoelectricity. Various compositions were evaluated examine impacts varying lignin concentrations, types electrolytes, concentrations crosslinkers, electrolyte on thermoelectric performance hydrogels. optimized lignin-derived hydrogel, infiltrated with a 6 M KOH electrolyte, demonstrates high conductivity (226.5 mS/cm) superior Seebeck coefficient 13 mV/K. results remarkable power factor (3831 µW/m·K 2 ) that leads impressive Figure merit (ZT i (3.75), surpassing most existing state-of-the-art making it material reported until now. These findings underscore exceptional lignin-based realm energy harvesting applications. present contributes address challenges posed by effectively harnessing while reducing reliance fossil fuels minimizing gas emissions.
