Abstract

Carbon nanoparticles have been successfully synthesized from waste lignin via carbonization and base activation. The effect of base activation on lignin transformation to carbon nanoparticles was investigated. Carbon nanoparticles from waste lignin via carbonization and base activation were denoted as CNPs. The physicochemical properties of CNPs were comprehensively characterized through a Scanning electron microscope (SEM), X-ray diffraction (XRD), and Raman spectroscopy. The results revealed that the condition using 5 wt% of sodium hydroxide (NaOH) and carbonization at 700°C on N2 atmosphere exhibited the highly porous structure of carbon nanoparticles. In conclusion, the NaOH-treated CNPs led to the production of high specific surface areas and high micropore volumes.
