摘要

Currently, it is difficult to realize environmentally friendly synthesis of zeolites due to the use of the solvent. Therefore, it isof great importance to realize zeolite synthesis from iron ore tailings (IOTs) by a solvent-free method. In this work, in situformed zeolite crystals are self-assembled and IOTs are converted into hierarchically porous ZSM-5. After that, the productsprepared are characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, Fouriertransform infrared spectroscopy and nitrogen adsorption. The results demonstrate that the samples show well-defined crystallinityand have micro-/mesoporous structures. The BET surface area is estimated to be 319.809 m2 g−1 and the externalsurface area is 92.693 m~2 g~(−1), which indicate the as-synthesized ZSM-5 is a good hierarchically porous material. This workprovides a reference for green synthesis of hierarchically porous ZSM-5 from IOT.
