The main synthesis methods and research status of microstructural units for improving the hydrothermal stability of mesoporous MCM-41 molecular sieve were reviewed. The influence of different microstructure units on the hydrothermal stability of mesoporous molecular sieve MCM-41 was systematically analyzed. The microstructure Unit and mesoporous molecular sieve hydrothermal stability of the relationship between the microstructure of the unit to explain the mosaic structure or core-shell structure of hydrothermally stable mesoporous molecular sieve mechanism, and finally prospects of high hydrothermal stability of mesoporous molecular sieve The application prospects.
