Mesoporous Fe-MCM-41 materials were synthesized by using ionic liquid 1-cethyl-3-methylimidazolium bromide [C16mim]+Br-) as template at room temperature and characterized by X-ray diffraction, N2 adsorption-desorption, FT-IR, EPR, UV-Vis. Results show that these mesoporous materials possess high surface area. The pore size distributions of Fe-MCM-41 show that there are two types mesoporous. Part of iron atom still retain in the framework after removal of the template by calcination except those transferring to the wall surface. Fe species on wall surface are of high dispersion. This indicates that stable framework-iron containing mesoporous molecular sieves Fe-MCM-41 can be successfully synthesized.
