Abstract

A highly ordered mesoporous aluminosilicate molecular sieve, designated as MSAMS-4, has been synthesized via multistage recrystallization. Hydrothermal-stability tests revealed that MSAMS-4 has retained a well-ordered hexagonal-symmetry mesostructure both after treatment with 100 °C water for 120 h and after steaming at 800 °C for 6 h.Key words: aluminosilicates molecular sieves, mesoporous materials, multistage recrystallization, hydrothermal stability.
