Mesoporous molecular sieves SBA-15 are synthesized by conventional hydrothermal process using tetraethylorthosilicate(TEOS) as silicon source and triblock copolymer P123 as template.The synthesized samples are characterized by N2 adsorption-desorption,X-ray diffraction (XRD) and transmission electron microscopy(TEM).The results show that with SiO2/P123 ratio increasing,the pore volume and pore size of SBA-15 decrease.With the increasing of reaction solution acidity,the surface area does not change observably but the pore volume and pore size increase.The addition of co-solvents can increase the pore volume and pore size to a certain extent and PhMe3 is the best one.
