Abstract: Background: As lamellar clay, montmorillonite (MMT) has intercalation, swelling, and ion exchange properties. Silver nanoparticles were prepared using the chemical reducing method in montmorillonite as a solid support at room temperature. The biological approaches for synthesis of nanoparticles are better than chemical and physical procedures because of low energy and time expenditure, non toxic solvents and non dangerous material for environment.

Methods: In this work, green biosynthesis of silver-montmorillonite (MMT) nanocomposite is reported at room temperature, using water extract of Ziziphora tenuior L as reducing agent into the interlamellar space of MMT.

Results: The synthesized silver-montmorillonite (Ag/MMT) nanocomposite were characterized using ultraviolet-visible spectroscopy (UV-Vis), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and powder Xray diffraction (XRD). The UV-Vis spectra of the Silver-montmorillonite nanocomposite showed absorption peak at around 415 nm. SEM, XRD and TEM studies showed that the average particles size of Ag/MMT nanocomposite were about 21.79 nm and also XRD patterns indicated that the structure of the nanocomposite is face-centered cubic.

Conclusion: The results showed, green synthesis of silver-montmorillonite nanocomposite was have successfully carried out from the AgNO3/MMT suspension using water extract of Ziziphora tenuior L at room temperature. The XRD pattern showed that the silver-montmorillonite nanocomposite formed were crystalline in nature. Also The SEM and TEM results showed that spherical silver nanoparticles and average particles size were about 21.79 nm.
