In this study, centrifugally spun soda lignin (SL) nanofibers were prepared as precursors to produce lignin-based carbon nanofibers (LCNF) and activated carbon nanofibers (LACNF). The impact of concentration of spinning solution and rational speed on the spinnability and fiber diameters were systematically examined by scanning electron microscopy (SEM). The result showed that the produced fibers diameter was in the range of 0.47-2.36 μm. The effect of SL nanofiber diameter on its morphology and thermal properties during carbonization was obtained by SEM, thermogravimetric (TGA) and differential calorimetric scanning (DSC) analyses. Subsequently, the SL nanofibers were ease to transform into LCNF and further LACNF with highest specific surface area of approximately 1900 m 2 /g, which is superior to those of LACNF in previously prepared by electrospinning. It can be concluded that centrifugal spinning method is a facile and efficient technique to develop large scale production of lignin-based nanofibers and in particular LACNF with high specific surface area., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier B.V.
