Abstract

Silver nanoparticles (Ag-NPs) have been successfully prepared with simple and "green" synthesis method by reducing Ag(+) ions in aqueous gelatin media with and in the absence of glucose as a reducing agent. In this study, gelatin was used for the first time as a reducing and stabilizing agent. The effect of temperature on particle size of Ag-NPs was also studied. It was found that with increasing temperature the size of nanoparticles is decreased. It was found that the particle size of Ag-NPs obtained in gelatin solutions is smaller than in gelatin-glucose solutions, which can be related to the rate of reduction reaction. X-ray diffraction, ultraviolet-visible spectra, transmission electron microscopy, and atomic force microscopy revealed the formation of monodispersed Ag-NPs with a narrow particle size distribution.

摘要

银纳米粒子（Ag-NPs）已成功通过在含有和不含有葡萄糖作为还原剂的明胶水溶液中还原Ag(+)离子，采用简单且“绿色”的合成方法制备。在本研究中，明胶首次被用作还原剂和稳定剂。还研究了温度对 Ag-NPs 粒径的影响。结果发现，随着温度的升高，纳米粒子的尺寸减小。结果发现，在明胶溶液中获得的 Ag-NPs 的粒径小于在明胶-葡萄糖溶液中获得的粒径，这可能与还原反应的速率有关。X 射线衍射、紫外-可见光谱、透射电子显微镜和原子力显微镜揭示了形成具有窄粒径分布的单分散 Ag-NPs。
