Several samples of mesoporous silica were prepared via sol-gel chemistry in the presence of CTAB as template with variation of stirring intensity and aging time, ratios of CTAB/SiO2 and NH4OH/H2O in synthesis mixture. Effects of aging temperature, hydrothermal treatment and ter-Butanol addition to the synthesis mixture on the textural properties of obtained samples were also studied. Results of XRD, SEM, and N2 adsorption isotherm analyses shows particle size and morphology of mesoporous silica are influenced by synthesis conditions; although no significant change of pore size (
