Title: Synthesis and Characterization of Stable Framework-iron Containing Mesoporous Molecular Sieves Fe-MCM-41
Abstract: Mesoporous Fe-MCM-41 materials were synthesized by using ionic liquid 1-cethyl-3- methylimidazolium bromide ([C_(16)mim]~+Br~-) as template at room temperature and characterized by X-ray diffraction,N_2 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 cal- cination 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.
