The ordered mesoporous aluminosilicate molecular sieve (MASMS‐1) stable in the high‐temperature steam has been successfully synthesized from the assembly of diluted ZSM‐5‐type precursor with mesoporous MCM‐41. The material was characterized by XRD, N 2 adsorption‐desorption, FE‐SEM, TEM, FT‐IR spectroscopy and 27 Al MAS NMR techniques. This mesoporous material shows high stability in the high‐temperature steam [H 2 O ( ψ =20%) in N 2 at 800 °C for 4 h], which might be ascribed to the synergistic effect of both thick walls containing zeolite‐like five‐membered ring subunits and highly condensed surface silanol groups.
