摘要
Five samples of SiMCM-41, AlSiMCM-41, FeSiMCM-41, LaSiMCM-41 andAILaSiNCM-41 were synthesised and their good thermal stability was proved-by TG/DTAand XRD. All the samples were thermal stable up to abode 1150-1160 K. LaSiMCM-41 andFeSiMCM-41 showed better hydrothermal stability. Due to the cllalinel diameter within 1.5-10 urn, the synthesis ofmesoPOrous molecularsieve MCM41 by Mobil in 1992 anew new light on the conventional concept of SyntheSisofarelitCslll. For its POtential application, the studies on this novel matchal family are veryactive reCently, but few papers t'.ere published about their thennal and hydrithennal stability.
