Al-MCM-41 synthesis using Al-isopropoxide as Al source

摘要

Our studies emphasize that it can be obtain a good-quality Al-MCM-41 material, with well-resolved XRD patterns, high BET surface areas and acid properties in an range of Al mole fraction (Al/(Al+Si)) up to 0.063. It seems also that the presence of low amounts of Al in the framework prevents 'the deterioration of the long-range structural order as in the case of siliceous MCM-41 occurred.
