| Abstract: | The synthesis of mesoporous molecular sieves MCM-41 was accomplished successfully by using TEOS as silicon source, CTAB as structural template under acidic condition. The effect of pH values, CTAB/TEOS, H_2O/TEOS, the crystallization temperatures etc. on the synthesis of MCM-41 was also investigated in this article. All the samples were characterized by XRD. |
