Mesoporous molecular sieves such as hexagonally ordered MCM-41 have potential applications in catalysis, adsorption and separation, preparation of advanced materials, and molecular devices since they are firstly discovered in 1992. However, as compared with zeolites, the acidity and hydrothermal stability of these mesostructured materials are relatively low, which strongly affect their practical applications in industrial catalytic reactions of petroleum. Here it is systematically summarized that the research work on improvement of acidity and hydrothermal stability for ordered mesoporous materials, which include (1) the assembly of super acidic components into the mesopores; (2) the addition of inorganic salts, organic ammonium compounds during the synthesis of mesoporous materials or post-synthesis of mesoporous materials; (3) the synthesis of mesoporous materials from novel templates such as triblock copolymers; (4) the assembly of mesoporous materials from pre-formed zeolite structure-directing-agent(zeolite seeds solution) with zeolite primary and secondary building structure units.
