Synthesis and characterization of nanocrystalline micro-mesoporous ZSM-5 MCM-41 composite zeolite

الملخص EN

Nanocrystalline micro-mesoporous ZSM/MCM-41 composite was synthesized using alkaline treatment method and two step of crystallization in poly tetraflouroethylene (PTFE) lined autoclave.

The synthesized zeolites was characterized by X-Ray diffraction (XRD), Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), Atomic force microscopy (AFM), Fourier transport infrared (FTIR), and N2 adsorption-desorption (BET).

It was approved that the best results for alkaline leaching can be got with 1.5M NaOH solution.

High surface (BET) area of 630 m2/g with pore volume of 0.55 cm3/g has been got.

AFM reports showed a nano-level size for average particle size of 50nm.
