Sustainable Production of Cellulose Nanofibers from Miscanthus through Ionic Liquid Pre-treatment and Ultrasonic Processing
Short Introductive summary
Cellulose nanofibers (CNF) are promising nanomaterials derived from lignocellulosic biomass, offering high strength, biodegradability, and renewability for applications in biomedicine, construction, and sustainable packaging. This study introduces an eco-friendly method for producing CNF from Miscanthus × giganteus via ionic liquid ([DMBA][HSO4]) pretreatment, hydrogen peroxide bleaching, and ultrasonication. Freeze-dried pulps formed white aerogels within three days. Using Response Surface Methodology, sonication parameters were optimized to improve CNF morphology and reduce size. The method yielded CNF with diameters from 66–200 nm; however, low amplitudes (19.6%) did not achieve nanoscale reduction. Sonication amplitude had a greater effect on morphology than duration. XRD analysis showed that ionic liquid pretreatment, not sonication, primarily enhanced cellulose crystallinity. Overall, this approach offers a greener CNF production pathway and the ability for this process to also recover lignin further supports a circular biorefinery.
