Abstract

High crystalline nano-sized NH ₄-ZSM-5 zeolites with a wide SiO ₂/Al ₂O ₃ ratio range were directly synthesized through seed-induced approach. The products were characterized using X-ray powder diffraction (XRPD), scanning electron microscopy (SEM), Fourier transform infrared (FT-IR), N ₂-sorption experiment, thermal gravimetry (TG) analysis, ammonium temperature programmed desorption (NH ₃-TPD), inductively coupled plasma atomic emission spectroscopy (ICP-AES) and ²⁷Al and ²⁹Si MAS NMR. The crystal sizes could be controlled by simply adjusting the amount of seeding suspension. The as-prepared NH ₄-ZSM-5 can be converted the acid H-form by a single calcination.
