In this paper, we report the isolation of cellulose nanocrystals (CNCs). During the study, Allium sativam skin (garlic skin) was used to evaluate their potential for the synthesis of ZnO NPs. The remaining biomass of garlic skin was further processed to isolate cellulose. The purest form of the cellulose was obtained and further acid hydrolysis was carried out to obtain nanocrystalline cellulose (CNCs). Garlic skin was chosen because it is abundant and so far it has not been extensively investigated as a raw material option to produce CNCs as well as nanoparticles synthesis. Formation of CNCs have been confirmed X-ray diffraction (XRD) for crystal structure, Fourier transform infrared spectroscopy (FTIR) analysis was done for chemical groups and bonding, scanning electron microscope with Energy dispersive X-ray studies (EDX) was carried out to analyze the surface morphology and percentage composition of elements, transmission electron microscope (TEM) for particle size and shape, surface area and pore size of nanomaterials were calculated by Brunauer-Emmet-Teller (BET) analysis. The adsorption study was carried out for the removal of Methylene blue dye. Different concentration of dyes 10 ppm, 25 ppm and 50 ppm was taken during study. Result: The scanning electron microscope confirms the formation of the crystalline cellulose having average size 6.41 nm. Energy dispersive X-ray analysis states the formation of high purity of CNCs. BET analysis also confirms the increased surface area of CNCs than untreated cellulose. Different concentration of methylene blue dye was taken during study to check the adsorption efficiency of CNCs. The result showed that, the percent of MB removal increases by increasing adsorbent dosage and decreasing initial dye concentration.
