As reported in our previous study [32], mesoporous silicananoparticles.(MSN) were rapidly synthesized via hydrolysis and co-condensation.Of TEOS and C18TMS in an ethanol-water-ammonia system. The.Detailed procedures were as follows: C18TMS and TEOS were first dissolved.In 50 mL EtOH and sonicated for, 10 min then the mixture was.Added into the solutions containing ethanol deionized water, and ammonia.Here different, C18TMS / TEOS molar ratios (0.32 0.53 0.74) and,,,EtOH / H2O volume ratios (,,) 3.6 5.6 7.5 were used to tune the pore size.OfMSN. After the mixturewas stirred for 2 h at 25 ° C the solid, products.Were collected, by filtration washed with deionized water for several.Times and dried, at room temperature in air. Finally the resulted, silica.Surfactant composite powder was calcined at 550 ° C for 6 h to obtain.MSN.The scanning electron microscopy (SEM) images were obtained.Using a Hitachi S-4800 microscope operated at an acceleration voltage.
