摘　　要：Mesoporous Molecular Sieves were successfully synthesized by using the performed zeolite mordenite precursors as silica source. The synthesized samples were characterized by XRD, FT-IR , N_ 2 adsorption and desorption and hydrothermal treatment methods. The results demonstrated that the synthesized samples were similar to the conventional structure MCM-41 in the ordered hexagonal structure and were superior to conventional MCM-41 with respect to their higher hydrothermal stability. It is suggested that secondary structure units of mordenite zeolite were introduced into the mesoporous wall that makes the contribution of the highly hydrothermal stability of Mesoporous Molecular Sieves.Mesoporous Molecular Sieves were successfully synthesized by using the performed zeolite mordenite precursors as silica source.
