| چکیده | ||
| The preparation and production of silica nanoparticles via the sol-gel approach has been studied in this article with two types of deep eutectic solvents (DESs). The DESs were synthesized by means of choline chloride, Urea, and citric acid. Deep eutectic solvents is considered a environmentally friendly materials and they attract much attention recently. The determination of the nano-silica's structure by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (FESEM), Energy-dispersive X-ray spectroscopy (EDX), and Brunauer–Emmett–Teller (BET) analysis have been used to specify The physico-chemical properties. Regarding to analysis the surface area and pore volume of the SI structure in comparison with SII structure was higher while the particle size was smaller. This could be attributed to the role of acidic eutectic solvents in the production of metal oxide nanoparticles. These results revealed that SI structure favorite potential for adsorption and catalytic application due to favorite surface area, pore volume and porosity. | ||
