The objective of this research was to evaluate a novel technique of synthesis by solvent autoignition. The CNTs were synthesized using two methods of solvent autoignition: radiation assisted by a microwave oven and autoignition by muffle-furnace. Synthesized CNTs were examined by dynamic light scattering, UV-VIS spectroscopy, and Raman spectroscopy. The results indicate that the physicochemical properties of CNTs were influenced by synthesis method. Biochars obtained by autoignition through the muffle-furnace produced higher CNTs concentration and smaller hydrodynamic diameter and show a higher degree of wall graphitization, suggesting superior CNT quality. These results are promising for application in the construction industry and as a sustainable lignocellulosic residual biomass management solution.
