MCM-48 nanoporous silicates are attractive catalyst due to its well-order structure, high surface area, and narrow pore size distribution. Three-dimensional interconnected channel and large pore diameter of MCM-48 can prevent pore blocking and allow a bulky molecule to diffuse through. Generally, to enhance the redox property of MCM-48, a transition metal is introduced. However, bimetallic materials provide more advantages due to simultaneously increasing two abilities, such as the redox property and hydrothermal stability. In this study, a series of Fe-Ce and Fe-Ti incorporated into MCM-48 was successfully synthesized from silatrane precursor via sol-gel method. The synthesized materials were characterized by X-ray diffraction spectroscopy (XRD), N2 physisorption, diffuse reflectance UV-vis spectroscopy (DRUV), X-ray fluorescence spectroscopy (XRF), transmission electron microscopy (TEM), and scanning electron microscopy (SEM). The optimum synthesis conditions and effect of metal content were investigated in detail.
