Synthesis of zeolite–magadiite composites: Effects of co-solvent and aluminum source

The one-pot synthesis of ZSM-5–magadiite, ZSM-23–magadiite, and ZSM-5–ZSM-23–magadiite using isopropylamine and 2-propanol as an organic structure-directing agent and co-solvent, respectively, was studied. Zeolite mixtures were prepared by adding 2-propanol (0 to 10 wt%) to the reaction solution. The intergrowth of composites was observed when 2-propanol was introduced as a co-solvent into the reaction mixture. Synthesized samples were characterized by X-ray diffraction, field-emission scanning electron microscopy, energy-dispersive X-ray spectroscopy, and thermogravimetric analysis. The results revealed that the amount of 2-propanol and source of aluminum influenced the nature of the zeolite–magadiite composites formed.
