| Ordered mesoporous materials have been the subject of intense research since the discovery of the M41S class of materials by Mobil group. These materials are characterized by high surface areas, large pore volumes, and large pore sizes (2-50 nm). Among the mesoporous materials, MCM-48 possesses a continuous three dimensional pore system that is thought to provide favorable mass transfer kinetics. Thus, it seems to be an attractive candidate for catalytic applications. A rapid and reliable synthesis of transition metal ion (Al3+, Fe3+ etc.) containing MCM-48 is a challenge. A synthesis based on the Stöber process was successfully adopted to prepare a series of Al and Fe-MCM-48 materials. The powder X-ray diffraction patterns of the calcined MCM-48 feature several reflections below 2θ < 6° that indicate the existence of mesoscopic order in these materials. The textural and electronic properties of these materials are currently under investigation. Finally, these materials will be tested for the oxidation of several organics such as cyclohexane, cyclohexanone, etc.
