Abstract
Highly ordered Fe-MCM-48 was synthesized by a mixed template method under low molar ratio (0.17:1) of mixed surfactants to silica. The effect of various factors, such as Fe sources, the amount of Fe salt, Si sources, surfactant/SiO2, crystallization temperature and crystallization time on the synthesis were discussed in detail. The Debye-Huckel theory, the theory of salts formation, the local effective surfactant packing parameter theory and the charge balance theory were used to explain the reason that various factors can affect the product structure reasonably. The optimum synthesis conditions for Fe-MCM-48 were obtained.
