Synthesis of Mesoporous Molecular Sieve MCM-41

Focused on the preparation and preparative conditions of MCM-41 such as the amount of templates(CTAB), water, the crystallization time, the crystallization temperature and aluminum sources. The optimum value of the above varieties was obtained: n(Na2O)/n(SiO2) = 0.18-0.24; n(CTAB)/n(SiO2) = 0.10-0.14; n(H2O)/n(SiO2) = 24 - 30; n(Al2O3)/n(SiO2) = 0-0.033.The crystallization time and the crystallization temperature is 12h and 140℃ , respectively. Characterization results obtained from the determination of XRD and SEM show that the products possess far similar structure properties to those standard ones reported in literatures.
