One of the known groups of mesoporous materials is MCM-41 that has been applied as catalyst for various chemical reactions. In the content of this study, using cetylytrimethylammonium bromide (CTAB) as surfactant, sodium silicate and tetraethylortosilicate (TEOS) as silica source mesoporous materials MCM-41 was synthesized by hydrothermal synthesis method and sonochemical synthesis method. The obtained results showed that MCM-41 synthesized by the sonochemical method had higher specific surface area and pore volume than those synthesized by the hydrothermal method. Also, the effects of silica source on the distribution of products were studied and sodium silicate was found to be more suitable for the synthesis of MCM-41. Based on determinated optimum conditions, MCM-41 supported Al, Co and Fe having different ratios of metal (Metal/Si: ratio 0.05, 0.1 and 0.2) was synthesized. It was observed that metal dispersion on MCM-41 was homogenous for all samples and its particles sizes were between 10 nm to 30 nm. Synthesized mesoporous materials were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersion spectroscopy (EDS) and Brunauer Emmett Teller (BET) surface area methods.
