Mesoporous silica MCM-41 (MS-MCM-41) was synthesized via a hydrothermal treatment using sodium silicate as a silica source extracted from wheat straw ash. The effect of aging temperature to the structure and physical properties of the mesoporous silica was discussed to provide the optimum preparation technique. The more ordered 2D hexagonal structure of mesoporous silica was obtained by applying the hydrothermal tteatment procedure. With increasing the hydrothermal aging temperatures from 80 degrees C to 120 degrees C, the pore volume and average pore size enlarged accordingly and the BET surface area increased from 724 to 1312 m(2)/g, respectively.
