Green Synthesis and the formation kinetics of silver nanoparticles in aqueous Inula Viscosa extract

Abstract

In this study, we present the production of silver nanoparticles in aqueous Inula Viscosa extract by the green synthesis approach at room temperature. The structural, and morphological properties as well as formation kinetics of the synthesized silver nanoparticles were characterized by UV–Vis, DLS, STEM, XRD, Raman, and FTIR measurements. Mono-dispersed and very stable silver nanoparticles with a size of 15 ± 5 nm and face-centered cubic crystal structure were synthesized in aqueous Inula Viscosa extract. The kinetic studies of silver nanoparticles formation in Inula Viscosa extract show that silver nanoparticle formation reaction reached an equilibrium within 24 h and fit in the first-order reaction kinetics. The results clearly show that the size of fabricated nanoparticles is independent of the dynamical formation process since the reaction time and initial silver ion concentration are not affected by the size and morphology of the produced particles.
