Direct synthesis of Zn-ZSM-5 with novel morphology

Zinc-containing ZSM-5 zeolite with novel morphology was firstly synthesized in a one-step route using [Zn(NH3)4]2+ aqueous solution as zinc resource and n-butylamine as template. The materials were characterized by XRD, SEM, diffuse reflectance UV–vis spectra, FTIR for pyridine adsorption. The results showed that the formation of this novel structure might be related to the introduction of [Zn(NH3)4]2+ aqueous solution and the zinc existent state in zeolite.
