Abstract: Highly ordered mesoporous aluminosilicate molecular sieve MSAMS-4 was synthesized via multistage recrystallization. The reaction product was characterized by XRD, N2 adsorption-desorption, FTIR spectroscopy and 27Al MAS NMR. The hydrothermal stability tests exhibit that MSAMS-4 retained a well-ordered hexagonal symmetry mesostructure both after being treated with 100 ℃ water for 120 h and streamed at 800 ℃ for 6 h.
