Cellulose nanocrystals (CNCs) as building blocks were widely used to produce renewable and sustainable nanomaterials. CNCs are mainly produced by inorganic acid hydrolysis such as sulfuric, hydrochloric, nitric, phosphoric acids, etc. However, there are some drawbacks for inorganic acid hydrolysis such as harsh corrosion of equipment, severe environmental pollution, large water usage and so on. Herein, we reported a green and sustainable method for the preparation of CNCs via a one-step treatment based on a deep system solvent (DES) system of FeCl3-catalyzed choline chloride and oxalic acid dihydrate (F-DES). Due to its low melting point, this F-DES can be easily obtained at a lower temperature. Results shows that CNC samples (F-CNC) could be successfully isolated from bleached eucalyptus Kraft pulp (BEKP) with a high yield (over 70%). Also the DES could be recovered from the reaction solution by a simple evaporation process with high recovery rate ( %). Thermogravimetric analyses revealed that the onset decomposition temperature for the obtained F-CNC was 321°C, which was much higher than that of the CNCs produced from the same raw BEKP by sulfuric acid hydrolysis. Therefore, the FeCl3-catalyzed deep eutectic solvent treatment could be a sustainable and economically feasible method for the production of CNCs with high thermal stability.
