摘要：
本研究采用绿色合成方法，在室温下的水溶液Inula Viscosa提取物中制备了银纳米颗粒。通过UV-VIS、STEM、XRD、Raman和FTIR测量对合成银纳米颗粒的结构、形态特性及生成动力学进行了表征。在水溶液Inula Viscosa提取物中合成了尺寸为15±5 nm、具有面心立方晶体结构的单分散且非常稳定的银纳米颗粒。Inula Viscosa提取物中银纳米颗粒生成的动力学研究表明，银纳米颗粒生成反应在24小时内达到平衡，并符合一级反应动力学。结果清楚表明，所制备纳米颗粒的尺寸独立于动态生成过程，因为反应时间和初始银离子浓度并未影响生成颗粒的尺寸和形态。
英文摘要：
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, morphological properties as well as formation kinetics of the synthesized silver nanoparticles were characterized by UV-VIS, STEM, XRD, Raman and FTIR measurements. Mono-dispersed and very stable silver nanoparticles with size of 15$\pm$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 the equilibrium within 24 h and fit in the first-order reaction kinetics. The results clearly show that the size of fabricated nanoparticles is independent on the dynamical formation process since the reaction time and initial silver ion concentration did not affect on size and morphology of the produced particles.
