In this work, lignin/zinc oxide nanocomposites with excellent UV-absorbent performance were prepared through a novel hydrothermal method using industrial alkali lignin (AL) as raw materials. AL was first modified by quaternization to synthesize quaternized (QAL). The QAL/ZnO different contents then via facile one-step QAL and zinc nitrate hexahydrate hexamethylenetetramine in aqueous solution. nanocomposite possessed an average diameter of ∼100 nm showed synergistic performance. particle...
In this work, lignin-decorated ZnO composite was prepared via an in situ synthesis method using industrial alkali lignin (AL). First, the AL modified by quaternization to prepare quaternized (QAL). The microstructure and optical properties of QAL/ZnO were characterized scanning electron microscopy (SEM), transmission (TEM), X-ray diffraction (XRD), UV–vis photoluminescence (PL) spectroscopy. These results showed that possessed a flowerlike structure excellent synergistic UV-absorbent...

Carbon/transition metal oxide composites exhibit promising potential as electrode materials for energy storage, but regulating their interfacial composite structures remains a formidable challenge. In this work, we develop lignosulfonate-assisted synthesis strategy to fabricate porous carbon-supported MnO2 (LSC/MnO2-2) with robust interface asymmetric supercapacitors (ASCs). The functionalized lignin carbon, achieved through π–π interactions lignosulfonate, exhibited improved dispersibility,...
