论文摘要
在这项研究中，我们通过室温下的绿色合成方法介绍了在水溶液维斯科萨提取物中的银纳米颗粒的产生。合成银纳米颗粒的结构，形态学特性以及形成动力学的特征是UV-VIS，STEM，XRD，RAMAN和FTIR测量值。单分散且非常稳定的银纳米颗粒，大小为15 $ \ pm $ 5 nm，面部中心的立方晶体结构在水溶液中合成了inula inula viscosa提取物。银纳米颗粒形成的动力学研究表明，银纳米颗粒形成反应在24小时内达到平衡，并适合一阶反应动力学。结果清楚地表明，由于反应时间和初始银离子浓度不会影响产生的颗粒的大小和形态，因此制造的纳米颗粒的大小独立于动态形成过程。
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.
