Abstract

Tobacco stems constitute a large amount of waste biomass generated during tobacco production, and their recycling is of great significance to the environment and the conservation of resources. In this study, an efficient, inexpensive, and less toxic strategy is reported for recycling waste tobacco stem, wherein the spherical tobacco stem nanocellulose (STsN) with a size of 10 to 100 nm was prepared from waste stems using a NaOH/urea/thiourea aqueous system. The morphology of STsN was characterized using scanning electron microscopy. The crystal structure of STsN was determined using X-ray diffractometry. The nanocellulose exhibited the crystal structure of cellulose II. Fourier-transform infrared spectra of the STsN indicated that STsN retained the typical chemical structure of cellulose. The thermal properties of STsN were investigated by thermogravimetry. It is concluded that the STsN had better thermal stability than cellulose. The product has potential for practical application with high thermal stability requirements, such as transistors and batteries.
