| This article examined the preparation and production of silica nanoparticles using the sol-gel method with two types of deep eutectic solvents (DESs). The DESs were synthesized from choline chloride, urea, and citric acid. To determine the physicochemical properties of the nano-silica, X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, energy-dispersive X-ray spectroscopy, and Brunauer–Emmett–Teller analysis were employed. Analysis revealed that the SI structure (choline chloride (ChCl)-citric acid) exhibited a higher surface area and pore volume compared to the SII structure (choline chloride (ChCl)-urea), while also demonstrating a smaller particle size. This difference can be attributed to the role of acidic eutectic solvents in metal oxide nanoparticle production. These results suggest that the SI structure demonstrates promising potential for adsorption and catalytic applications. | ||
