Rapid and green synthesis of silver nanoparticles via sodium alginate media


Balavandy, Sepideh Keshan and Shameli, Kamyar and Zainal Abidin, Zurina (2015) Rapid and green synthesis of silver nanoparticles via sodium alginate media. International Journal of Electrochemical Science, 10 (1). pp. 486-497. ISSN 1452-3981


This study focuses on influence of accelerator in rapidly and green synthesis of silver nanoparticles (Ag-NPs) with the natural polymeric matrix. Silver nitrate, sodium alginate (Na-Alg) and sodium hydroxide have been used as silver precursor, stabilizer/reducing agent, and accelerator reagent, respectively. The resulting products have been confirmed to be Ag-NPs smaller than 20 nm using powder X-ray diffraction (PXRD), UV-visible spectroscopy (UV-vis), Fourier transform infrared (FT-IR) spectroscopy as well as transmission electron microscopy (TEM) and scanning electron microscopy. The colloidal solutions of Ag-NPs obtained at different volumes of NaOH show strong and different surface plasmon resonance (SPR) peaks, which can be explained from the TEM images of Ag-NPs and their particle size distribution. Compared with other synthetic methods, this work is rapid, green and simple to use. The newly prepared Ag-NPs may have many potential applications in chemical pharmaceutical and food industries.
