The shells of tree important food nuts and the relevance of valorizing nutshells are growing. The potential value of argan nutshells (ANS), which are one of the primary byproducts of the argan oil industry and are wasted to the tune of approximately 60,000 tons each year, has received attention in research related to the same industry. This paper suggests using argan nutshells particles rich in nematic ordered cellulose for producing cellulose nanocrystals (CNC-II) with a rectangular shape via the chains self-assembly in acid hydrolysis that is useful in many fields of applications. In the experimental results, the chemical composition of ANS was described; moreover, the morphologies of ANS after each chemical treatment were studied. Furthermore, the morphological properties investigated via scanning electron microscopy (SEM) and the structural properties determined via X-ray diffraction (XRD), Fourier-transformed infrared (FTIR), and the thermal properties via thermogravimetric analysis (TGA) confirm the successful regeneration of nanostructured cellulose (II) with a high crystallinity index (84%) where the XRD was attributed to the CNC type II. Furthermore, the AFM and STEM show a rectangular shape with an average size of 286 nm diameter. |
