摘要：

Mesoporous molecular sieves SBA-15, and MAS-7 and MTS-9 synthesized from zeolite primary structure units, are characterized by high-resolution transmission electron microscopy (HRTEM). Direct observation of the micropores within these mesoporous materials via HRTEM is presented. And nanorange ordered microporosity is found for the first time within the pore walls of MAS-7 and MTS-9, which might be the key to the high hydrothermal stability of the mesoporous materials.
