Abstract

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, N2 adsorption-desorption, FE-SEM, TEM, FT-IR spectroscopy and 27Al MAS NMR techniques. This mesoporous material shows high stability in the high-temperature steam [H2O (ψ=20%) in N2 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.
