Abstract
Benzo-18-crown-6 is employed to work as both reducing and stabilizing reagent in the reaction for synthesis of silver nanoparticles. Silver nanoparticles are analyzed using transmission electron microscope and UV–visible spectroscopic technique. The silver nanoparticles prepared in this way are uniform and stable, which can be stored at refrigerator for 5 months. Appearance of surface plasmon band at 420 nm indicated the formation of silver nanoparticles. Highly monodispersed stable silver nanoparticles were obtained within 3 min of microwave irradiation. Through transmission electron microscopy, silver nanoparticles were observed to be spherical.
Highlights
In the last few years, there have been considerable efforts dedicated to the preparation, characterization and applications of metal nanoparticles (NPs) (Pal and Deb 2012a, b, c, d, e; Pal et al 2012, 2013; Pal et al 2009; Shah et al 2010; Bahgat et al 2012; Kannan et al 2012; Karuppuchamy et al 2012; Nafees et al 2012)
We find that benzo-18-crown-6 can work as both reducing and stabilizing reagent in the synthesis of AgNPs
The advantage of microwave-mediated synthesis over the conventional heating is the improved kinetics of the reaction generally by one or two orders of magnitude, due to rapid initial heating and the generation of localized hightemperature zones at reaction sites (Liu et al 2005)
