Mesoporous materials are insufficient to withstand the severe process conditions. But, in case that the crystalline zeolites are incorporated into the silica frameworks, these can be expected to advance their physicochemical properties. So, we suggest two synthesis of meso/microporous materials. One is the sequential synthesis of MCM-41 and MFI-type zeolite by two step treatments using TPABr and C16TMAB. The other is the synthesis of mesoporous silica and alumino-silicate ZSM-5 crystals, prepared by the solid rearrangement process in the framework of TPAOH-impregnated mesoporous precursor such as MCM-41 and SBA-15, containing nano-structured carbons in the pore channels. |
