Dear Dr. Abdelkrim Rebiai,

here below a method to obtain SiO2-coated desert sand particles in a quite simple way.

The fine raw sand was obtained from Kubuqi desert and was cleaned with deionized water only. To obtain the SiO2-coated sand, the sand first needed to be positively charged; therefore, 5 g sand in 100 mL ethanol was added to 50 mL 0.14 M cetyl-trimethyl ammonium bromide (C19H42BrN) aqueous solution and the mixture was stirred for 1 h. After that, the pH value of the solution was adjusted to 12 using ammonium hydroxide. Next, 10 mL tetraethoxysilane (TEOS) was added drop-wise to the above solution. Under continuous and vigorous stirring for 10 h, the hydrolysis of TEOS directly resulted in the formation of sand@SiO2 composite particles. The resulting product was achieved after fully rinsing with deionized water and drying at 60°C.
