A new approach for the synthesis of mesoporous molecular sieve was reported. Using tetraethyl orthosilicate (TEOS) as silica sources, and cetyltriethylammonium bromide as templating agent, the mesoporous silica MCM-41 could be easily synthesized in glycerol medium in the presence of different organic amine by solvothermal synthesis process. The attained samples were characterized by XRD, N2 ad-sorption-desorption, TG-DTG and FT-IR. The experimental results show that the samples synthesized by organic amine, such as ethylenediamine and triethylamine have high-order and narrow pore diameter distribution in comparision with those obtained with inorganic alkali of sodium hydroxide.
