Descrição: This chapter discusses the rapid synthesis of high quality MCM-41 silica through ultrasound irradiation. High-quality MCM-41 silica has been sonochemically synthesized in a relatively short time and characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), nitrogen sorption, and hydrothermal treatment. It reveals that ultrasound promotes the condensation of surface silanol groups among micelles and accelerates the formation of MCM-41 framework. The as-synthesized MCM-41 silica, whose pore size shows a very narrow distribution, possesses a thicker wall and enhanced thermal stability as compared to those prepared with conventional methods.
