摘　　要：Mesoporous molecular sieves AIMCM-41 were synthesized by static hydrothermal crystallization using cetyltrimethylammonium bromide as template, water glass as silica source and pseudoboehmite as aluminum source. The XRD results showed that the prepared AlMCM-41 mesoporous molecular sieves had high relative crystallinity and long-range order. The relative crystallinity was greater than 27% after calcination at 900 ℃ for 2 hours and was still greater than 14% after ageing in steam at 800 ℃ for 2 hours. The results indicated that both thermal and hydrothermal stabilities of the mesoporous molecular sieves AIMCM-41 were good.Mesoporous molecular sieves AIMCM-41 were synthesized by static hydrothermal crystallization using cetyltrimethylammonium bromide as template, water glass as silica source and pseudoboehmite as aluminum source.
