- 中文摘要: Four common mesostructured aluminosilicates (e.g. AlMCM-41, AlMCM-48, AlMSU-1 and AlSBA-15, Si/Al = 7.5) with different pore framework structures were prepared via post-synthetic method utilizing aluminum isopropoxide as the aluminating agent and characterized by 27Al MAS NMR, XRD, N2-adsorption isotherm and NH3-TPD. It was found that, on the basis of the above analysis results, AlMCM-41, AlMSU-1 and AlSBA-15 retained more mesoporosity than cubic Al/MCM-48 after exposure to pure steam at 800 oC, which may be responsible for their much higher activities in bulky 1,3,5-triisopropylbenzene (TIPB) conversion.
