Abstract

Ordered mesoporous silica SBA-15 materials were synthesized by using Pluronic P123 (non-ionic triblock copolymer, EO 20PO 70EO 20) as a template, under acidic condition. These materials were characterized by nitrogen adsorption-desorption measurements, scanning electron microscopy (SEM), X-ray diffraction (XRD) and thermo-gravimetric analysis (TGA). It was found that structural properties can be adjusted by the different temperatures and times in the reaction solutions. Obtained samples have high specific surface area (>600 m 2 g -1 ) and developed mesoporous structure. Also, our measurements have shown that these materials have a certain amount of micropores..
