Abstract :
Deep eutectic solvents (DESs) have always been attractive to scientists due to their wide range of applications, a great interest in diverse fields including nanotechnology due to their unique properties as new green solvents. It used large-scale for chemical and electrochemical synthesis nanomaterial. DESs have had also active role in improving the size and morphology of nanomaterial during synthesis stage. This paper reports on chemical methods using for decrease size and purification of commercial TiO2 powders by deep eutectic solvents (DESs). This method was based on the dissolution of TiO2 powders in a deep eutectic solvent (DES), followed by precipitation of TiO2 nanostructures from the DES upon introduction of antisolvent. Under appropriate conditions, the ethanol and water content of the antisolvent and the injection time of the TiO2 containing DES, the morphology of the resulting TiO2 nanostructures can be readily controlled. The present method can be readily extended to produce versatile nanostructures of other functional materials. We also studied morphology of TiO2 nanoparticles. Size of TiO2 particles were conformed ~60 nm.
