摘要

Aluminated hierarchical silicalite-2 with both large particle size and high external surface area was prepared by aluminating silicalite-2 under the protection of TBA⁺ cations in a mild alkaline solution. The textural and acidic properties of thus formed material (Z11-meso) were characterized by SEM, TEM, XRD, N₂ adsorption, FTIR, NH₃-TPD, and ²⁷Al NMR spectroscopy. The resulting hierarchical Z11-meso contained mainly tetrahedral coordinated aluminum species with low Brønsted/Lewis ratio (B/L) while preserved the zeolitic structure. Owning to the high external surface area (S_ext), hierarchical porous structures and low B/L ratio, Z11-meso outperformed the microporous ZSM-11 counterparts in methanol to hydrocarbons in terms of both activity and stability.
