Wheat straw and corn stalk are agricultural residues which are abundant, inexpensive, and readily available source of renewable lignocellulosic biomass. The aim of this study was to prepare cellulose nanocrystals (CNCs) from wheat straw and corn stalk, and to compare their characteristics. To achieve these goals, the CNCs obtained from hydrolysis were characterized in terms of physical, structural and morphological properties. Particle size distribution and atomic force microscopy (AFM) images showed that the CNC from corn stalk (CNC-CS) was more uniform than that from wheat straw (CNC-WS); FTIR spectra implied that acid hydrolysis treatment had no effect on the chemical structure of CNCs. Moreover, the crystallinity of CNC-CS was higher than that of CNC-WS and thermal stability of CNC-WS was observed to be similar to CNC-CS.
