摘要

A series of zirconium doped Mobil Five (MFI) zeolites were synthesized hydrothermally with silicon to aluminium plus zirconium ratios of 100 and 200 and with different Al to Zr ratios. The MFI zeolite phase was identified by XRD and FT-IR analysis. UV-vis (DRS) and TG analyses suggested isomorphous substitution of Zr in the framework of MFI structure. The specific surface area, pore volume and pore size of the synthesized samples were investigated by the nitrogen adsorption method, while morphology was examined using scanning electron microscopy.
