英文摘要：

Porous molecular sieves, as a kind of important inorganic materials, have been greatly concerned by researchers. The development of the research, such as structure, methods of preparation, improvement, applications and so on are reviewed, which based on the different porous molecular sieves, involving improved microporous molecular sieves, improved mesoporous molecular sieves and hierarchical-porous composite molecular sieves. The strongpoints and deficiencies of porous materials synthesized by different methods are analyzed. The prospects for porous molecular sieves are expected.
